I am using two Updatepanels in ASP.NET AJAX and as soon as there is some event in first updatepanel, it will get refreshed at that time I want my second Updatepanel getting refreshed too. How can I do that ?
View 2 RepliesI'm writing a small photo album application and having some problem of refreshing the original images in the updatepanel. I have two updatepanels, one on the left contains a gridview to display image thumbs, and the other in the right contains an image control. When click on the thumb on the left, the file name of the image on the right will be inserted using the CommandArgument value. However, when I clicked the thumb, nothing happened. Instead of refreshing an image, I put a label and it worked fine. The following is my aspx side code and code behind.

I have an asp UpdatePanel, an asp panel, an asp timer, and an asp label on my web page, as you know the whole idea of updatepanel is trying to implementing partial page rendering mechanisem, however, it is not the case in my scenario, here is the code:

and on the pageload event, i assign:

strangely, the labl1 does update the time without causing the whole page post back, but the panel does cause the whole page refreshed, and the asp panel contains asp buttons and those buttons are generated dynamically by code behand c# file, am i missing sth here or the nature of asp:panel will cause the whole page post back?
I have an extra asp.net label to show success or error message after the add, update or delete a row, but using the BlockUI, I am unable to do it, cause the label is somehow not refresh even if i put it under the BlockUI.
View 1 Replieshow to update treeview using updatepanel?I am binded my treeview using xml datasource,periodically the datasource was updated,so i am used updatepanel in treeview but, it is not updating while changes came.when i refresh that page ,it is update
View 2 RepliesI have read several post on the TreeView is not/partly working with the UpdatePanel, but none of them mention that an update (triggered by a timer) causes creation of multiple javascript functions in the HTML header. In Mozilla Firefox this a memory leak. I have created a test webapplication to demonstrate the issue we encounter.

Periodically a rash of occurrences of the following error happen. I believe they're the result of hack attempts. Whether that's the case or not, my question is how can I handle the error? I want to avoid unhandled exceptions. The TreeView control is just
a standard .Net TreeView control, not a custom one. If you suggest a code solution, please code it in VB.Net as that's what I'm using.

I have a treeview which will be generated dynamically which need to be displayed on left side and when user clicks on a node it need to open a page on the right side of the same page. and each node has different aspx page. so whenever user selects a node the page details should be displayed on the right side .we can use an iframe on the page which will display the different pages clicked on the node.Is there any alternative i can use to display different pages based on the user selection on the right side without using iframe.

View 6 RepliesI have an ASP.Net 3.5 application with a menu. The menu is set to an xmlDataSource. The xmlDataSource is given the menus for the user as a dataset. The xmlDataSource uses an xsl transform file.Here is the code behind:
[Code]....
My problem is, when another user logs into the system, he/she gets the previous user's menus. This is based on time somehow, because if you wait long enough after another user has left a page, you'll get the proper menus.Could it have something to do with page caching? Is there something I'm missing with menus?
I have been at this for two weeks now without any success but I know I have to get a solution to move forward with my design. Is there any way to bind data from a SQLDataSource to a Hiddenfield or Textbox WITHOUT binding via the data controls like gridview, formview, datalist, etc. I do not want to use any of those controls. I need to do inline binding. Please provide the working code example. The hiddenfield or textbox would be named eid. The SQLDataSource name is GetDataEid. Again, if you reply and you submit code I can try please provide the full working solution. These do not work. They have already been attempted:
<asp:HiddenField ID="HiddenField1" runat="server" Value="<%#Container.DataItem("FieldName") %>" />
<input type="hidden" id="hdnId" name="hdnId" runat="server" />
and write the following code in your page load method
hdnId.Value=yourDbValue.ToString();
asp:HiddenField ID="hid" runat="server" Value='<%#Eval("column name") %>' />
<asp:TemplateField>
<ItemTemplate>
<asp:HiddenField ID="HiddenFieldTime" runat="server" Value='<%# Bind("Time") %>' Visible="False" />
</ItemTemplate>
</asp:TemplateField>
