After Popup .Want to select a row on popup grid then click on ok button and put the value on TextBox fo the parent grid.How to set value on Parent Grid.
I guess you should use the row command event handler of the grid, if I got you right:
OnRowCommand="RowCommand"
Then you can add a button to the grid:
<asp:LinkButton ID="LnkButton" runat="server" CommandName="setValue" CommandArgument='<%# Eval("id")%>'>Set value</asp:LinkButton>
And a method to handle it:
protected void RowCommand(Object sender, GridViewCommandEventArgs e)
if (e.CommandName=="setValue")
[do something with e.CommandArgument and close dialog]

So, I have a select query where I am taking the value selected from a drop down list on one page and using that in SELECT queries for others. The issue I am having is that when I navigate from one page to the next, the cookie is not used in the query. If anyone can figure out why, that'd be great.
My code for both pages is below:

I am a beginner in Asp.Net. I have a datalist populated with images. What i want is to know what image was clicked so that I can redirect the user to a different page as per the image clicked inside the datalist.

I was using this file as a reference
http://code.msdn.microsoft.com/VBASPNETGridView-19039173
I would like to follow the sorting function in that demo.
But when I build a simple page . my gridview header is not a hyperlink
I already have sortExpression. but the header stays as regular text (not clickable).
This is the ASPX of my TEST aspx.

When i use this code it displays the Header as links - is that what your after?
<asp:GridView ID="GridView1" runat="server" OnSorting="GridView1_Sorting" OnRowDataBound="GridView1_RowDataBound" AutoGenerateColumns="False" AllowSorting="true">
<Columns>
<asp:CommandField ShowEditButton="True" />
<asp:CommandField ShowDeleteButton="True" />
<asp:BoundField DataField="PersonID" HeaderText="PersonID" ReadOnly="False" SortExpression="PersonID" />
<asp:TemplateField HeaderText="LastName" SortExpression="LastName">
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("LastName") %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("LastName") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
Gridview is made sortable with the AllowSorting property:
<asp:GridView ID="GridView1"
runat="server"
-->AllowPaging="True" <--
AllowSorting="True" >
<Columns>
{insert your columns}
</Columns>
</asp:GridView>
That will make your headers clickable. The sample page didn't set AllowSorting on the control. The code later in the page shows where they set this in code-behind:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
' The Page is accessed for the first time.
If Not IsPostBack Then
' Enable the GridView paging option and
' specify the page size.
gvPerson.AllowPaging = True
gvPerson.PageSize = 15
' Enable the GridView sorting option.
--> gvPerson.AllowSorting = True <--
' Initialize the sorting expression.
ViewState("SortExpression") = "PersonID ASC"
' Populate the GridView.
BindGridView()
End If
End Sub
Hope that helps. :)
I have three asp net text boxes that will contain search criteria for searching a table. I would like the search to work like Google. When the enter key is pressed to have the click event on the "Enter" button fire. The click event never fires. What can I do to get it to fire?

and here is the behind code method:
protected void EnterKeyPressed_Click(object sender, EventArgs e)
{
ReloadData();
this.Multiview1.ActiveViewIndex = 0;
}
At a quick glance, have you tried removing the return false here:
$("#<%=SVParentCategoryLinkTitle.ClientID %>").keydown(function (e) {
if (e.which == 13) {
__doPostBack("#<%=EnterKeyPressed.UniqueID %>", "");
return false;
}
})
check out this question and answer, if it helps: Default button not working in asp.net panel
the DefaultButton is used to capture the Enter key press if the focus is already inside the panel, for example you must have moved the focus to an input field like the text boxes inside the panel. if the focus is not there it won't work.
I have a button placed on each row of my GridView. When the user presses the button I would like to display a simple popup where I show text. Part of the text is the DataKeyName related to the specific row.
I already tried with ModalPopupExtender myMPE triggered by the button and I used a Panel myPanel as PopupControlID. The problem is that the TextBox txtPanel of the Panel where I place the DataKeyName value is always empty. I tried to debug without myMPE and the txtPanel of the Panel is correctly filled. I guess it makes a mess with the postbacks.
Anybody knows a solution?
Are you doing a manual refresh of the UpdaePanel on the modal popup panel ? If not, try manually refreshing the updatePanel & set its updateMode to Conditional.
Check above example
