Here are is my column class and i've added this code to my radgrid
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Telerik.Web.UI;
namespace EFDemo.Views.Controls
{
public class HpGridButtonColumn : GridButtonColumn{
public string LinkedTab;
public override void InitializeCell(System.Web.UI.WebControls.TableCell cell, int columnIndex, Telerik.Web.UI.GridItem inItem)
{
//if (inItem is GridHeaderItem)
//{
// cell.Text = this.DataField;
//}
//if (inItem is GridDataItem)
//{
// string ID = (string) inItem.OwnerTableView.DataKeyValues[inItem.ItemIndex]["CustomerID"];
// cell.Controls.Add(new LiteralControl(ID));
//}
base.InitializeCell(cell, columnIndex, inItem);
}
public override GridColumn Clone()
{
HpGridButtonColumn col = new HpGridButtonColumn();
//you should override CopyBaseProperties if you have some column specific properties
col.CopyBaseProperties(this);
return col;
}
protected override void CopyBaseProperties(GridColumn FromColumn)
{
base.CopyBaseProperties(FromColumn);
((HpGridButtonColumn)FromColumn).LinkedTab = LinkedTab;
}
}
}
protected void HPRadgrid_ColumnCreating(object sender, GridColumnCreatingEventArgs e)
{
if ((e.ColumnType == typeof(HpGridButtonColumn).Name))
{
e.Column = new HpGridButtonColumn();
}
}
Problem is the property [linkedTab] is not being restored on postback. It is null.
Also, the clone method on the column is not being called. I assume this is why the property is not being restored.

How to add the Title "State" in the middle of the ToolBar for the PickerRenderer in Xamarin ios(Forms) ?
You could check the following code
using System;
using xxx.iOS;
using Foundation;
using UIKit;
using Xamarin.Forms;
using Xamarin.Forms.Platform.iOS;
[assembly: ExportRenderer(typeof(Picker), typeof(MyiOSPickerRenderer))]
namespace xxx.iOS
{
public class MyiOSPickerRenderer : PickerRenderer, IUIPickerViewDelegate, IUIPickerViewDataSource
{
string SelectedValue;
public MyiOSPickerRenderer()
{
}
public nint GetComponentCount(UIPickerView pickerView)
{
return 1;
}
public nint GetRowsInComponent(UIPickerView pickerView, nint component)
{
return Element.Items.Count;
}
[Export("pickerView:viewForRow:forComponent:reusingView:")]
public UIView GetView(UIPickerView pickerView, nint row, nint component, UIView view)
{
UILabel label = new UILabel
{
//here you can set the style of item!!!
TextColor = UIColor.Blue,
Text = Element.Items[(int)row].ToString(),
TextAlignment = UITextAlignment.Center,
};
return label;
}
[Export("pickerView:didSelectRow:inComponent:")]
public void Selected(UIPickerView pickerView, nint row, nint component)
{
Control.Text = Element.Items[(int)row];
SelectedValue = Element.Items[(int)row];
}
protected override void OnElementChanged(ElementChangedEventArgs<Picker> e)
{
base.OnElementChanged(e);
if (Control != null)
{
SelectedValue = Element.Items[0];
UIPickerView pickerView = (UIPickerView)Control.InputView;
pickerView.WeakDelegate = this;
pickerView.DataSource = this;
UIToolbar toolbar = (UIToolbar)Control.InputAccessoryView;
UIBarButtonItem save = new UIBarButtonItem("Save", UIBarButtonItemStyle.Done, (object sender, EventArgs click) =>
{
Control.Text = SelectedValue;
toolbar.RemoveFromSuperview();
pickerView.RemoveFromSuperview();
Control.ResignFirstResponder();
});
UIBarButtonItem Title = new UIBarButtonItem("States", UIBarButtonItemStyle.Done, null);
UIBarButtonItem cancel = new UIBarButtonItem("Cancel", UIBarButtonItemStyle.Bordered, (object sender, EventArgs click) =>
{
toolbar.RemoveFromSuperview();
pickerView.RemoveFromSuperview();
Control.ResignFirstResponder();
});
UIBarButtonItem empty = new UIBarButtonItem(UIBarButtonSystemItem.FlexibleSpace, null);
toolbar.Items = new UIBarButtonItem[] { cancel, empty, Title, empty, save };
}
}
}
}
Can someone please help me how can i use special characters in ASP.Net identity?
The problem is that my users cannot register with special characters: č,ć,š,ž,đ.
When you try to enter this characters in registration, i get following error:
User name Krešo is invalid, can only contain letters or digits.
Where and how can i change this.
Here is the code:
using Microsoft.AspNet.Identity;
using Microsoft.Owin.Security;
using Microsoft.AspNet.Identity.EntityFramework;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class Pages_Account_Register : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btnPrijava_Click(object sender, EventArgs e)
{
UserStore<IdentityUser> userStore = new UserStore<IdentityUser>();
userStore.Context.Database.Connection.ConnectionString =
System.Configuration.ConfigurationManager.ConnectionStrings["SeminariConnectionString3"].ConnectionString;
UserManager<IdentityUser> manager = new UserManager<IdentityUser>(userStore);
IdentityUser user = new IdentityUser();
user.UserName = txtKorisnickoIme.Text;
if(txtLozinka.Text == txtPotvrdaLozinke.Text)
{
try
{
IdentityResult result = manager.Create(user, txtLozinka.Text);
if(result.Succeeded)
{
var authenticationManager = HttpContext.Current.GetOwinContext().Authentication;
var userIdentity = manager.CreateIdentity(user, DefaultAuthenticationTypes.ApplicationCookie);
authenticationManager.SignIn(new AuthenticationProperties(), userIdentity);
Response.Redirect("Pocetna.aspx");
}
else
{
litStatus.Text = result.Errors.FirstOrDefault();
}
}
catch (Exception ex)
{
litStatus.Text = ex.ToString();
}
}
else
{
litStatus.Text = "Lozinke moraju biti identične.";
}
}
}
You should be able to change this behaviour as follows:
var manager = new UserManager<IdentityUser>(userStore); // existing code
var validator = manager.UserValidator as UserValidator<ApplicationUser>;
if (validator != null) validator.AllowOnlyAlphanumericUserNames = false;
Should validator turn out to be null, then debug a little to find the actual type used at runtime.
This is the code to my Master Page cs file. For some reason when I run my default page, I get an error that says "object reference not set to an instance of an object."
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace Theming.MasterPages
{
public partial class Main : System.Web.UI.MasterPage
{
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
string selectedTheme = Page.Theme;
HttpCookie preferredTheme = Request.Cookies.Get("PreferredTheme");
if (preferredTheme != null)
{
selectedTheme = preferredTheme.Value;
}
if (!string.IsNullOrEmpty(selectedTheme))
{
ListItem item = ThemeList.Items.FindByValue(selectedTheme);
if (item != null)
{
item.Selected = true;
}
}
}
switch (Page.Theme.ToLower())
{
case "darkgrey":
Menu1.Visible = false;
TreeView1.Visible = true;
break;
default:
Menu1.Visible = true;
TreeView1.Visible = false;
break;
}
}
protected void ThemeList_SelectedIndexChanged(object sender, EventArgs e)
{
HttpCookie preferredTheme = new HttpCookie("PreferredTheme");
preferredTheme.Expires = DateTime.Now.AddMonths(3);
preferredTheme.Value = ThemeList.SelectedValue;
Response.Cookies.Add(preferredTheme);
Response.Redirect(Request.Url.ToString());
}
}
}
The error appears to be at the switch statement but I can't figure out why. I've read on other posts that the value is assigning to the variable as null but I don't know why; I've got dark grey as an app theme. If anyone could please help me it would be very much appreciated.
I don't see Menu1 or TreeView1 defined anywhere in your markup. If those are in a content page, you can't access those in the MasterPage code-behind (there may be a way, but you can't directly access them the way you're trying to).
I have a UserControl that has some javascript I'd like to inject into a known ContentPlaceHolder.
I was hoping to do something like the following except when I append to add the control to found control I get an exception which says I cannot modify the control collection in the Init, Load or PreRender events:
"UserControl.ascx"
<%# Control Language="C#" %>
<asp:Checkbox runat="server" id="checkBox"/>
<app:JavascriptInjector runat="server" InjectInto="ScriptPlaceHolder">
$(function(){ $('#<%= checkBox.ClientID %>').click(function() { ... });
</script></app:JavascriptInjector>
"JavascriptInjector.cs"
using System;
using System.Diagnostics;
using System.Linq;
using System.Web.UI;
using System.Web.UI.WebControls;
public class JavascriptInjector : PlaceHolder
{
public string InjectInto
{
get { return this.ViewState["InjectInto"] as string; }
set { this.ViewState["InjectInto"] = value; }
}
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
this.PreRender += this.__PreRender;
}
private void __PreRender(object sender, EventArgs e)
{
if (string.IsNullOrEmpty(this.InjectInto))
{
goto performRegularlly;
}
var injectInto = this.FindControlRecursively(this.Page);
if (injectInto == null)
{
goto performRegularlly;
}
injectInto.Controls.Add(this);
return;
performRegularlly:
Debug.WriteLine("performing regularlly");
}
private Control FindControlRecursively(Control current)
{
var found = current.FindControl(this.InjectInto);
if (found != null)
{
return found;
}
foreach (var child in current.Controls.Cast<Control>())
{
return this.FindControlRecursively(child);
}
return null;
}
}
I figured it out. The following JavascriptInjector class will work, although I don't know what the implications are of calling the render method in the PreRender. Also think I may need to do something to figure out which type of HtmlTextWriter that the base application is using.
"JavaScriptInjector.cs"
using System;
using System.IO;
using System.Linq;
using System.Web.UI;
using System.Web.UI.WebControls;
public class JavascriptInjector : PlaceHolder
{
private bool performRegularlly;
public string InjectInto
{
get { return this.ViewState["InjectInto"] as string; }
set { this.ViewState["InjectInto"] = value; }
}
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
this.PreRender += this.__PreRender;
}
protected override void Render(HtmlTextWriter writer)
{
if (this.performRegularlly)
{
base.Render(writer);
}
}
private void __PreRender(object sender, EventArgs e)
{
if (string.IsNullOrEmpty(this.InjectInto))
{
goto performRegularlly;
}
var injectInto = this.FindControlRecursively(this.Page);
if (injectInto == null)
{
goto performRegularlly;
}
performRegularlly = false;
using (var stringWriter = new StringWriter())
using (var writer = new HtmlTextWriter(stringWriter))
{
base.Render(writer);
writer.Flush();
injectInto.Controls.Add(new LiteralControl(stringWriter.GetStringBuilder().ToString()));
}
this.Controls.Clear();
return;
performRegularlly: this.performRegularlly = true;
}
private Control FindControlRecursively(Control current)
{
var found = current.FindControl(this.InjectInto);
if (found != null)
{
return found;
}
foreach (var child in current.Controls.Cast<Control>())
{
return this.FindControlRecursively(child);
}
return null;
}
}
I have SharePoint 2007 on Windows Server 2003 SP1 (in VM).
I am running the web application here: http://vspug.com/nicksevens/2007/08/31/create-custom-field-types-for-sharepoint/
Part of it is below:
using System;
using System.Collections.Generic;
using System.Text;
using System.Web.UI.WebControls;
using Microsoft.SharePoint;
using Microsoft.SharePoint.WebControls;
namespace CustomControl
{
public class customfieldcontrol : BaseFieldControl
{
protected TextBox txtFirstName;
protected TextBox txtLastName;
protected override string DefaultTemplateName
{
get { return "CustomFieldRendering"; }
}
public override object Value
{
get
{
EnsureChildControls();
return txtFirstName.Text + "%" + txtLastName.Text;
}
set
{
try
{
EnsureChildControls();
txtFirstName.Text = value.ToString().Split('%')[0];
txtLastName.Text = value.ToString().Split('%')[1];
}
catch { }
}
}
public override void Focus()
{
EnsureChildControls();
txtFirstName.Focus();
}
protected override void CreateChildControls()
{
if (Field == null) return;
base.CreateChildControls();
//Don't render the textbox if we are just displaying the field
if (ControlMode == Microsoft.SharePoint.WebControls.SPControlMode.Display) return;
txtFirstName = (TextBox)TemplateContainer.FindControl("txtFirstName");
txtLastName = (TextBox)TemplateContainer.FindControl("txtLastName");
if (txtFirstName == null) throw new NullReferenceException("txtFirstName is null");
if (txtLastName == null) throw new NullReferenceException("txtLastName is null");
if (ControlMode == Microsoft.SharePoint.WebControls.SPControlMode.New)
{
txtFirstName.Text = "";
txtLastName.Text = "";
}
}
}
}
This line:
txtFirstName = (TextBox)TemplateContainer.FindControl("txtFirstName");
always returns null.
I removed base.CreateChildControls() but it still returns null.
Any assistance would be greatly appreciated.
Place your control's .ascx file right under CONTROLTEMPLATES folder and try.
