So I download your code into my test web project "WebSite1", greate, it works.
Then in your CS.aspx page,

<asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server"> <ContentTemplate>

Gridview Page value inside UpdatePanel
I have a GridView and DetailsView in a Master/Detail relationship inside an Update Panel.The GridView displays a set of records, and when a Select button in the GridView is clicked, the detailsview displays the record for edit.Initially the focus is on the GridView, and when the Select button is clicked, I want the focus to be on the first TextBox inside the DetailsView. This happens only when I remove the UpdatePanel from the form. If the Gridview/Detailsview pair is inside an updatepanel, the focus never goes to the DetailsView.How can I make the focus on the DetailsView inside an UpdatePanel
View 4 RepliesI have some problem with the AutoCompleteExtender when it's include in an UpdatePanel.
Scenario:
I have create a UserControl with TextBox, AutoCompleteExtender and a "Save" LinkButton and I put this Control in the InsertItemTemplate of a ListView.
The AutoComplete uses a Method that I have created in a webservice.
All works fine untill i place my ListView in an UpdatePanel.
The webmethod don't fired. The strange thing is that if i put the same Control also out of my ListView it seems to work, but i can't catch the linkbutton click.
I've got a fileupload control inside of a gridview so that each row (item from the database) can have an attachment associated with it. I've got a button next to the fileupload control (besides the default browse... button to select the file) to actually take the file and upload it to a file server. This works great if I use this button "Upload". However, underneath my gridview I have another imagebutton that is outside of the gridview, its just sitting on the form / page. The idea of this "Update" button is when end users make changes to the grid I can simply loop through the grid and update the values they have entered to the database. This also works great.
Now here is my issue assume a user has 3 rows in the grid view. On 2 of these rows he decides to add an attachment but he never clicks the "Upload" button he only uses the standard browse button to select the file. Now instead of clicking the "Upload" button that is on the grid view he ends up clicking the "Update" button outside of the grid thinking that it will save his attachments. So I decided to write code to grab the fileupload control from the grid using .FindControls("NameOfFileUploadControl") in my Update button loop where I loop through all the rows. Then I check if myFileUploadControl.HasFile property to see if there exists a file and if there does upload the file then continue with the code.
The issue is when I click this "Update" button .HasFile always returns false even though I can see the text string of the path in the fileuploadcontrol textbox (the standard one next to the browse button). Is it because this goes back to the page load event and checks if it is a post back? What causes this and how can I fix it? Im adding some code because im still confused with this
Protected Sub SaveGrid()
For Each Row As GridViewRow In Me.gvLineItems.Rows
Dim f As FileUpload = CType(Row.FindControl("fuAttachment"), FileUpload)
'todo: this part is not working
If f.FileName.Length > 0 Then 'returns 0 always
'this returns 0.
end if
if f.HasFile() then
'this also returns false
end if
Next
End Sub
This method gets called on a click of a button. The fileupload control is in an of a gridview that is wrapped inside of an UpdatePanel:
<asp:FileUpload Width="90px" Font-Size="xx-small" ID="fuAttachment" runat="server" />
I have implemented Sorting technique on Gridview but whole page is reload I have put in update panal but it's not working
View 1 RepliesI am using UpdatePanel, and I include a gridview inside the updatepanel, I want the grid to be refreshed when button1 or button2 of gridview being pressed.

The following is

Altough questions somehow similar to this have been asked for a number of times, but the question is still unsolved. Here is the question: I have a gridview which is contained in a tab container ajax control which itself is inside an updatepanel. Gridview works excellent and its corresponding methods are fired accurately, but when I enable paging, (e.g.) after I click on page 2, the gridview hides itself. here is my PageIndexChanging method:
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
GridView1.DataBind();
UpdatePanel2.Update();
}
Why paging causes gridview to stop working correctly? What can I do?
This is Vijay Reddy Chennadi. I have a problem with validation summary, which is not working properly inside a gridview (which is in an updatepanel).
View 4 Replies I am developing a user control. This user control is having 2 Dropdown controls and one textbox('txtCustomer'). I am using autocompleteextender for the text box. This 'txtCustomer' control populates the data based on the value selected in 2 dropdowns.
I need to pass the selected value of this 2 dropdown to my meb method. I am not using web service(.asmx page) for this application instead i am using page level web method. I tried to access the controls from the web method inside the Page. but all the identifiers and controls of the page returning null in the web mothod. I have analysed it is because the events "page_Load and page_Init" are not getting fired.
How to pass addtional parameters to AutoCompleteExtender's ServiceMethod.I am trying to create common web service method for all the autocomplete textboxes in my web apps.
I want to pass the source table name,the key to be retrived, and any filtring criteria to the web method.
I have a ImageButton inside a gridview. The gridview is inside update panel. i want to redirect to another page with the Clicking of the ImageButton. But it is not working inside update panel. what should i do?
View 1 RepliesI hope this is a really easy question but I'm struggling with it. I have a GridView that has an UpdatePanel within a TemplateField.
The idea is that the user can make simple alterations without a full page load being required.
I have simulated my page functionality in the following example, which simulates a database hit, gridview databinding and updatepanel functionality.
When you press any of the + or - buttons in the GridView, the form controls in the bottom UpdatePanel also post their contents back. I have seen this by using Firebug. On my real page however this is causing excessive bandwidth and is nearly the same as a full postback.
how I can force ONLY the appropriate UpdatePanel's contents to postback for processing, rather than all the UpdatePanels?? I've tried experimenting with Triggers but just can't get it working properly.

I have put my gridView inside an UpdatePanel with Timer control for auto refresh.The gridView has a linkButton column which is bounded to referenceNo column from database.
On click of this link button i want a panel to get visible. This Panel contains details corresponding to the referenceNo shown in differnt controls (mostly texboxes). Do i necessarily need to put the panel inside the Update Panel.If not how do i do it?
I have tried putting panel outside UpdatePanel, but it doesn't show panel on clicking the linkbutton nor does the values are updated inside this panel (if panel's visibility is set to true by default for testing purpose).
Autocompleteextender not working inside an user control tried all ways. i have a custom function.. inside the cs file itself like the following :-
