I have a partial View which contains a TextArea.
When i Render this parital view in my main view page the Text Area is coming disabled (but it not graying out) and not allowing any entry to be typed there.
//---Here are the code segement from my partial view---
<div id="AddComment" style="display:none">
<fieldset>
<legend>Add Comment</legend>
<p><label> Comment for:</label>- <select id="Station"></select></p>
**<%=Html.TextArea("UserComment", new { rows = 5, cols = 65})%>**** (this text area is the problem)
<p><input type="button" id="addComment" onclick="SaveComment()" value="Save" /></p>
</fieldset>
</div>
//-----end of code segment -----------------------
Please help
Thanks in advance.
I got the probem resolved. its was not the fault of the partial view Rendering.it was basically the script written on the main page to block the backspace keypress.
//--------------------below line of code prevents the browser to raise a backspace key press outside the editor---// //document.attachEvent('onkeydown', function(evt) { evt.returnValue = false; }); //-----------------------------------------------------------------------------------//...
once i removed this line thing started working. thanks you all for helping me

I am trying to have multi-coloured textarea on my page.
So basically I am planing have one textarea input and one <p> object. When user type in textarea, the <p> will be updated with jQuery, as soon as user type any letters in textarea.
Similar to Stackoverflow.
When the user finishes typing, he will select a text from the textarea and click the red or blue button.
The system will read the selected text, find the index of starting text and append
<span> style='color:red;'>
at the end of the text add
</span>
To be honest, I am not sure this is the best way to do it. I have seen
lots of RichText editor but they don't have any save button.
Anyway.
So far what I did:
<div class="row">
Red
Blue
<form asp-action="Save" method="post">
<textarea rows="10" style="width:100%" id="DetailText" name="DetailText">
This email and any files whom this email is addressed. <span> style='color:red;'>This suppose to be red</span>
Any unauthorised use, retention, distribution, copying or disclosure is strictly prohibited.
If you have received this email in error)
</textarea>
</form>
<hr />
#Html.Raw("<p id='viewText'></ p >");
<script src="~/lib/jquery/dist/jquery.js"></script>
<script>
$(document).ready(function () {
$("#viewText").text($("#DetailText").val());
$("#DetailText").on('input',function () {
$("#viewText").text( $("#DetailText").val());
});
});
ISSUE Html.Raw() doesn't complie the text and shows HTML code instead. style='color:red;'>This suppose to be red
I have 2 strange problems. I have a large form with lots of input fields. That works fine. I want to add a slide toggle at the bottom which changes a variable that will affect styles on the whole form.
My first problem is that the variable will not display until the slide toggle is clicked.
HTML
<mat-slide-toggle [(ngModel)]="ifPrint" name="ifPrint" id="ifPrint" ></mat-slide-toggle>
<div>
{{ifPrint}}
</div>
COMPONENT
export class PrintReviewDetailsComponent implements OnInit {
ifPrint = true;
}
the ifPrint variable is blank on page load
The second problem is
when the slide toggle is clicked the div containing the variable shows as true but when I click the toggle to the off position the ifPrint variable stays as true and does not change.
I have created a blitz and it is working fine there with the same code so I am unsure as why I am having these issues on my page.
The console says:
Error: No value accessor for form control with name: 'ifPrint'
EDIT: I updated the stackblitz to include the html of the form and now it is not working.
Your updated stackblitz couldn't recreate the issue which you shared... But from your question, the following 2 issues are addressed for a form and styling is also done:
the toggle value was not displayed by-default until the toggle was clicked
the toggle value didn't change when you toggled it
the style is now being updated based on the toggle value
relevant TS:
model:any;
constructor(){
this.model = {name: '' , age: null, ifPrint: false};
}
relevant HTML:
<form (ngSubmit)="formSubmit()" #demoForm="ngForm" >
<div [ngClass]="model.ifPrint === true ? 'trueClass' : 'falseClass'">
<input type="text" placeholder="Enter Name" #name="ngModel" [(ngModel)]="model.name" name="name" />
<br/>
<input type="number" placeholder="Enter Age" #age="ngModel" [(ngModel)]="model.age" name="age" /> <br/>
<mat-slide-toggle #ifPrint #age="ngModel" [(ngModel)]="model.ifPrint" name="ifPrint"></mat-slide-toggle> {{model.ifPrint}} <br/>
</div>
<button type="submit"> Submit </button>
</form>
check a minimal, working demo here for what you're trying... hope it helps...
I removed everything in your template except the mat-slide-toggle and it works as expected.
I believe the issue is because your html template is referencing methods or properties that your component does not have, or trying to access a property of null or undefined somewhere is causing the issue.
Check your console for the errors and if you fix those up, the slide toggle should work as expected.
I feel as though this this is a simple question, but can't find an answer anywhere. We've got an interface we're trying to move to an ASP.NET control. It currently looks like:
<link rel=""stylesheet"" type=""text/css"" href=""/Layout/CaptchaLayout.css"" />
<script type=""text/javascript"" src=""../../Scripts/vcaptcha_control.js""></script>
<div id="captcha_background">
<div id="captcha_loading_area">
<img id="captcha" src="#" alt="" />
</div>
<div id="vcaptcha_entry_container">
<input id="captcha_answer" type="text"/>
<input id="captcha_challenge" type="hidden"/>
<input id="captcha_publickey" type="hidden"/>
<input id="captcha_host" type="hidden"/>
</div>
<div id="captcha_logo_container"></div>
</div>
However all the examples I see of ASP.NET controls that allow for basical functionality - i.e.
public class MyControl : Panel
{
public MyControl()
{
}
protected override void OnInit(EventArgs e)
{
ScriptManager.RegisterScript( ... Google script, CSS, etc. ... );
TextBox txt = new TextBox();
txt.ID = "text1";
this.Controls.Add(txt);
CustomValidator vld = new CustomValidator();
vld.ControlToValidate = "text1";
vld.ID = "validator1";
this.Controls.Add(vld);
}
}
Don't allow for the detailed layout that we need. Any suggestions on how I can combine layout and functionality and still have a single ASP control we can drop in to pages? The ultimate goal is for users of the control to just drop in:
<captcha:CaptchaControl ID="CaptchaControl1"
runat="server"
Server="http://localhost:51947/"
/>
and see the working control.
Sorry for the basic nature of this one, any help is greatly appreciated.
Although you may want to look into user controls, the following page has an example of doing this using a web control. http://msdn.microsoft.com/en-us/library/3257x3ea.aspx The Render() method does the output of the actual HTML for the control.
There are a couple of ways to do it. You can make a custom control, or a user control. I think you will find it easier to do a user control. It lets you lay out parts of your control as you would a regular page. Here is some example documentation: http://msdn.microsoft.com/en-us/library/26db8ysc(VS.85).aspx
By contrast a custom control typically does all of the rendering in code (as your example you show). It is harder to make your first control in this way.
I am writing a form using jQuery and encounter some difficulties.
My form works fine in static page (html).
However, when I use the form in dynamic page(aspx), the form does not behave correctly.
I cannot append items to the form and call the form.serialize function.
I think the error occurs when a form is inside another form (.aspx code needs to enclosed by a form tag).
What should I do?
Let me give a simplified version of my code:
<form name="Form1" method="post" id="Form1">
some content
<form name="form_inside">
<input name="fname" type="text" />
</form>
</form>
jQuery code:
$("#form_inside").append($("<input type='text' name='lname'>"));
When the user submits,
$("#form_inside").serialize();
// it should return fname=inputfname&lname=inputlname
I want to append element to "form_inside" and serialize the form "form_inside".
The form "Form1" is required by the aspx and I cannot remove it.
Could you just serialize the fields inside Form1?
I don't know anything about ASP, but it seems that you're not doing a straightforward "submit" anyway - so does it really matter if the fields aren't within their own separate form?
You could possibly group the fields you're interested in within a <div> or something, e.g.:
<div id="my-interesting-fields">
...
</div>
then substitute #form-inside with #my-interesting-fields where appropriate - is that helpful at all?
Edit
OK, a quick glance at the jQuery code suggests that serialize() depends on the form's elements member.
I suppose you could hack this in a couple of different ways:
Copy all elements from #my-interesting-fields into a temporary <form> that you dynamically create outside Form1, then call serialize() on that. Something like:
$("#Form1").after("<form id='tmp-form'></form>").
append("#my-interesting-fields input");
$("tmp-form").serialize();
Or, create an elements member on #my-interesting-fields, e.g.
$("#my-interesting-fields").elements = $("#my-interesting-fields input");
$("#my-interesting-fields").serialize();
I haven't tried either of these, but that might give you a couple of ideas. Not that I would necessarily recommend either of them :)
Because you can't have nested <form> tags you'll need to close off the standard dotnet form tag like below:
<script type="text/javascript">
$(document).ready(function() {
$("#form_inside").append($("<input type='text' name='lname'>"));
$("#submitBtn").click(function() {function() {
var obj = $("#form_inside *");
var values = new Array();
obj.each(function(i,obj1) {
if (obj1.name && !obj1.disabled && obj1.value) {
values.push(obj1);
};
});
alert(jQuery.param(values));
}); });
});
</script>
<form id="form1" runat="server">
<div>
<div id="form_inside" name="form_inside"> <input name="fname" type="text" /><input type="button" id="submitBtn" /></div>
</div>
</form>
jQuery.param on a array of form elements will give you the same results as .serialize()
so you get all elements in div $("#form_inside *) then filter for elements then on the result jQuery.param will give you exactly what you need
I am new to jQuery, trying to populate a GridView or Telerik RadGrid using jQuery. Not sure how to go about it and unable to find any examples. Any help is appreciated. Thanks.
Essentially I am trying to display a modal window with a textbox and button. The user enters a search criteria presses the button and a gridview in the same modal window is populated with the results.
The user than selects records in the grid presses another button and the selected users are inserted into the database table, modal window is closed and a grid on the parent page is refreshed showing the new added users.
<input type="button" id="btnAddNewUserj" value="Add New User" />
$(document).ready(function() {
$("#btnAddNewUserj")
.click(function() { ShowNewUserDialog(); return false });
$("#btnSearch")
.click(function() { FindUsers(); return false });
});
function ShowNewUserDialog() {
$("#newuserDialog").dialog({ modal: true, bgiframe: true }).dialog("open");
}
function FindUsers() {
// HOW TO DO THIS?
// Show selectable list of users from the database in grid.
}
<div id="newuserDialog" title="Add New User" style="display:none;">
<div>
<input id="txtSearchFor" type="text" />
<input id="btnSearch" type="button" value="Search" class="Button" /></div>
<p> DISPLAY RESULTS HERE </p>
<div style="margin:10px 6px;">
<input type="button" id="btnjAdd" value="Add" class="Button" />
<input type="button" id="btnjCancel" value="Cancel" class="Button" />
</div>
</div>
A couple of thoughts here. You cannot populate a GridView or Telerik Grid using jQuery. jQuery is a client side technology and those two grids are server side.
You can use jQuery to hit a web service and build out and HTML table with the results (which is basically what a GridView does).
I'm guessing however, that you would be better served just using native GridView databinding. You can use a .Net UpdatePanel around the grid if you want to prevent full post backs.
I think telerik is not the answer.
Use telerik radgrid's client side binding, see this for an example: http://demos.telerik.com/aspnet-ajax/grid/examples/clientbinding/defaultcs.aspx
Note that sample shows how to bind to a WCF Web Service and an ADO.NET Data Service. There are other samples around.
Other variations of binding: http://demos.telerik.com/aspnet-ajax/grid/examples/client/declarativedatabinding/defaultcs.aspx
