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

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:

this is my project, i am using visual studio 2010 and my coding language is vb. I am new to this and it will be safe to say that i don't know much of it yet.
I have a login page where the head of department enters his detail(employee number, employee name), selects his department and submits the information to see the result in other web form i.e all the employees that are under his department out of all the employees working for the company.
Because i don't know the code, i am getting all the employees of every department in the gridview instead of getting the employees for the department that was selected from the dropdown list.
here is my code for the first page

Please tell me the process and the code and also where to put it, i am not very familiar with all this. Its kind of an emergency.
You can just store the selected item text in onw variable, like the below:
dim selText as string = DropDownList1.SelectedItem.Text
and on the click of submit button, perform your required tasks and then redirect page to another page along with the department name. Like the below code:
Response.Redirect("Page2.aspx?department=" + selText)
and on the second page i.e. Page2.aspx, just receive this value in query string, using below code.. wherever it is necessary either on page load or at your required place.
If Request.QueryString("department") <> Nothing Then
dim departmt as string = Request.QueryString("department")
End If
And use the above variable's value in your database query and get the related data to the department selected in the previous form.
I hope it will help you. :)
You can also save selected item text in Session. Afterward you can get this value from any page in your project:
Session("department") = DropDownList1.SelectedItem.Text
You also can use this value directly in your SqlDataSource on Page2:
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString11 %>"
ProviderName="<%$ ConnectionStrings:ConnectionString11.ProviderName %>"
SelectCommand="SELECT * FROM [employee database] WHERE Department LIKE #depart">
<SelectParameters>
<asp:SessionParameter DefaultValue="%" Name="depart" SessionField="user"
Type="string" />
</SelectParameters>
</asp:SqlDataSource>
I created a web user control & placed a gridview inside an update panel. I added this control to my webform but I cannot see the grid inside design view. I just see controls which are outside the update panel. Everything works fine when I view it in browser or remove update panel from the user control.
Is there someway to show my grid? Its confusing to see a blank space instead of the grid control in design view.

I have an aspx web page contains jquery mobile, I don't know why, whenever I call UpdatePanel.Update() in my code a white page appears as a result! of course the page is not empty because when I view source code (ctrl+u) all content are available. The strange point is for one call in a page, 2 ajax requests submit so two different responses received either two different post parameters. Post in first request is like this:
ScriptManager: UpdatePanel1|grdRequests$ctl03$btnCancel
__ASYNCPOST: true
__EVENTARGUMENT: nothing
__EVENTTARGET: nothing
__EVENTVALIDATION: value here
__LASTFOCUS: nothing
__VIEWSTATE value here
and response is like this:
1|#| |4|5451|updatePanel|UpdatePanel1|
but in second request there is no ScriptManager and ASYNCPOST parameteres, also in response only old content could see no more data. any idea?

Where are you binding your gridview..
You need to bind that in
private void Page_Load()
{
if (!IsPostBack)
{
// Need to Bind your grid here
}
}
I dont know why but when I removed updatepanel works ok.
Work on Asp.Net C# VS08.

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]
