Hi,
I am currently building aproject management application. My current issue lies with a dynamic table which refreshes each time i choose a different project (from a dropdown). I used to create my controls (in the dynamic table) on PageLoad. This worked fine but however, the viewstate was retained when i chose another project eventhough i tried almost everything from EnableViewstate = false to many others...
So, the quick fix was to actually create the dynamic controls in the "selectedIndexChanged" event of the project dropDown. This worked great. However, i am having a problem to updated data in one of these dynamic textboxes. If i change a value in the dynamic texbox and then click on "Save" button, i lose the viewstate of this textbox and it reverts to its previous value. Moreover, i do have dynamics dropdowns in the same table and they work fine, passing the changes.
Can you please help me fix that out?
Thanks beforehand dear friends.

whenever a control is added through controls.add() function, it goes through init,load and prerender. Add the dynamic textbox to the table or page before you set the property. this will enable the textbox to participate in the viewstate.
Dim txtBox As New TextBox
Table.Controls.Add(txtBox)
txtBox.Text = "ABCDE"

Hi all,
I have a gridview with select, that then loads my detailsview, the detailsview I use to create new entries, update existing and delete. All works but the gridview does not get refreshed.
The gridview uses a sqldatasource to get populated, and then the detailsview uses another sqldatasource to populate according to the gridview's selectedDataKey, the thing is that the second sqldatasource updates the database so the first sqldatasource does not reflect the changes, how do I get the first sqldatasource to reload, do I need to reload the entire page again or is there a better way of doing it?
Thanks in advance

Usually, if you do a post back the select method should get called again. You may have a caching issue. In my use of gridviews, I often cache the select results, so I don't have to call sql every time the user does a next or previous page click. The down side is you have to expire the cache when things get updated so the gridview will show the updated data. If you have not setup caching then there is some other problem.
Hope that helps.

After you make changes call DataBind() method of GridView1.
Example
GridView1.DataBind();

Hi Folks,
In my project i need to display the various menu's for different type of user also that we have using treeview for menu.the project developed in the VS 2003 and now we are migrating it to VS 2005 project. so we decided to use ASP .net Tree view control.
This is my code:
<asp:TreeView ID="TreeView1" runat="server" ImageSet="Arrows" Style="z-index: 102;
left: 24px; top: 32px; position: absolute;" Height="72px" Width="72px">
<ParentNodeStyle Font-Bold="False" />
<HoverNodeStyle Font-Underline="True" ForeColor="#5555DD"/>
<SelectedNodeStyle Font-Underline="True" ForeColor="#5555DD" HorizontalPadding="0px"
VerticalPadding="0px"/>
<Nodes>
<asp:TreeNode ShowCheckBox="False" Text="Reports" Value="Room Actions" Expanded="false"> </asp:TreeNode>
</Nodes>
</asp:TreeView>
It will throw an error:
inner Exception :
{"Using TreeView.HoverStyle requires Page.Header to be non-null (e.g. <head runat=\"server\" />)."}
outer Exception:
{"Error executing child request for Guest.aspx."}
This page is call by Server.Transfer method.
If you faced like this problem or if you have a solution for this please respond me.

Try
document.getElementById("btnsubmit").style.visibility = "hidden";
|
|
|
|
|
you can do it like:
//hide
document.getElementById("TextBox1").style.display = "none";
//show
document.getElementById("TextBox1").style.display = "block";

So your web.config looks like this:
<configuration>
<system.web>
<sessionState
mode="InProc"
timeout="60" />
</system.web>
</configuration>
??
What are you setting the session values to blank? I would think in the session_end event you would set them to null so the memory would be freed. There is no reason to initialize them to blank. In your code check to see if the session varable is null or Nothing if you are using VB.net

Ascii value for enter key is 13. You need to write OnKeyDown javascript event for your textbox and call function. Check event.KeyCode is 13, if yes use controlname.focus() to set focus to other textbox.
