I want to display ListView row count on how many user, but i only got 0 value.
Example code:
Response.Write("Total User in List: " + ListView1.Items.Count());
Thanks for help.
NOTE: I'm placing it on .cs Page load
Sorry for the raw data,
I didn't insert/add using code i just populate it manually on database
Put your code inside IsPostBack and then try
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
ListView1.DataSource = listUsers;
ListView1.DataBind();
Response.Write(ListView1.Items.Count);
}
}
In .NET i have a gridview which has to display on the mainpage with default settings. So i put it in pageload code. In the same page i have a "List" button; people choose date etc. and when they press the button gridview loads data from another stored procedure. I put that code under List button event. But after people press List button and gridview comes with the needed data, if they press something else (because of page refresh itself) gridview turns back to default settings.
How do i keep the gridview with wanted data?
protected void Page_Load(object sender, EventArgs e)
{
opsbelgegridview.DataSource = DB.OpsHavuzGetir();
opsbelgegridview.DataBind();
protected void listelebtn_Click(object sender, EventArgs e)
{
opsbelgegridview.DataSource = DB.OpsHavuzDetayListeleBtn(tarih1.ToString("yyyy-MM-dd"), tarih2.ToString("yyyy-MM-dd"), durumdd.SelectedItem.Text.ToString(), islemtipdd.SelectedItem.Text.ToString());
opsbelgegridview.DataBind();
You can use IsPostBack() and only load the initial grid on the first load of the page. Then if the grid data changes it will stay.
private void Page_Load()
{
if (!IsPostBack)
{
opsbelgegridview.DataSource = DB.OpsHavuzGetir();
opsbelgegridview.DataBind();
}
}
I have a textbox "txtName" listbox "listNames" and button "btn_Add". Now i want to populate the textbox with the name selected from the listbox on button click.
I am using asp.net and c#. please help.
do as below
protected void Page_Load(object sender, EventArgs e)
{
if(!IsPostBack)
{
//load listbox items here
}
}
if you load data on page load, in every post back your listbox will load again and again, you will lost the selection. Do as above to load data only first time page load. now you can get the list box selected items in button click event.
But this in your button.
txtName.Text = listNames.SelectedItem.Text;
Try this,
On code behind button click event.
txtText.Text = drpDwn.SelectedValue; // This is for ID
txtText.Text = drpDwn.SelectedItem.Text; //This is for Text
Put this on your code behind
protected void Page_Load(object sender, EventArgs e)
{
listNames.Items.Add("listboxItemValue1","Listbox Item Text 1");
listNames.Items.Add("listboxItemValue2","Listbox Item Text 2");
}
protected void btn_Add_Click(object sender, EventArgs e)
{
txtName.Text = listNames.SelectedItem.Text;
}
and this on your Asp,net page
<asp:button ID="btn_Add" runat=server" OnClick="btn_Add_Click" />
Use
textbox.Text= listbox.SelectedItem.ToString();
I have this web application which is supposed to move rows up and down on button click, but it does only when I close the webpage and re run my program from Visual Studio.
protected void Page_Load(object sender, EventArgs e)
{
if (Page.IsPostBack)
{
DataView view = (DataView)SqlDataSource1.Select(
DataSourceSelectArguments.Empty);
DataTable result = view.ToTable();
}
}
Is this all I need ?
You can use the CommandName to trigger the functionality of your button clicks.
Example: http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.linkbutton.commandargument.aspx
You need to use a button click event. You logic is currently in the page load event, that's why its only firing once
You could also remove the if postback which would also work but is not the recommended solution
protected void Page_Load(object sender, EventArgs e)
{
DataView view = (DataView)SqlDataSource1.Select(DataSourceSelectArguments.Empty);
DataTable result = view.ToTable();
}
How can i make a button work such that it clears up all text boxes of pop up at a same time ...
Is there a single line of code which can perform the above function?
I tried this
protected void AddNext_Click(object sender, EventArgs e)
{
AccountNumber.Text = null;
AccountTitle.Text = null;
PinNumber.Text = null;
CreationDate.Text = null;
Balance.Text=null;
AccountTitle.Text = null;
}
But is there a better way to Get all text boxes blank ??
this works if you want ALL textboxes on your page to be cleared on the click of a button:
protected void Button1_Click(object sender, EventArgs e)
{
foreach (TextBox i in this.Page.Form.Controls.OfType<TextBox>().ToList())
{
i.Text = null;
}
}
i'd be careful with this tho, as it will clear every textbox that is located on your page. But apart from that, this does what you asked for.
Find the form it's in and call reset() function on it in JavaScript onclick of button.
