View 1 RepliesForms Data Controls :: OnTreeNodePopulate Not Working On IE?
Oct 20, 2010I have an strange problem on a TreeView. Some of the nodes are being populated dynamically setting PopulateOnDemand = true and using the corresponding method for the OnTreeNodePopulate event. Everything works perfectly on Firefox and Chrome but does not work on Internet Explorer.
It seems that callbacks for this node populations are not working on IE. My site uses .Net 4.0
AJAX :: Using UpdateProgress As A ModalPopup / Disabling Webform While UpdateProgress Is Running
May 2, 2010I have a webform that works the following way:
1. Button_openPanel will display panel Step2Panel through ModalPopupExtenderStep2.
2. Button_runThread (inside Step2Panel) will close Step2Panel and will then run a lengthy process server-side. This lengthy server-side process will cause the UpdateProgress control to be displayed.
Similar to the ModalPopup, I want to disable the whole page while the UpdateProgress control (with its animation gif) is running. Currently, the UpdateProgress is displayed, but I can click Button_openPanel (or anything else) which will cause the application to break.
Is this possible?
This is basically all the code. I stripped anything that was unneeded:
[Code]....
The code-behind is basically this:
[Code]....
Everything's working pretty good now, but I need to disable everything while the time-consuming process is running and UpdateProgress is displayed.
I was thinking of displaying the UpdateProgress control as a a sort of ModalPopup, but I'm not sure if it's possible. If not, then the alternative would be to disable Button_openPanel while the time-consuming process is running and UpdateProgress is displayed.

Web Forms :: TreeView TreeNodePopulate Event Called Before Page_Load?
May 20, 2010I have a TreeView on a page which I will populate the nodes on demand and a checkbox, and they are in the same updatepanel. I can dynamically add new nodes to this treeview. But when I click the checkbox which will cause a postback, the TreeNodePopulate is called before the Page_load and it will regenerate the nodes that was added before. I was very confused how could this be happened. Is this related with PopulateOnDemand and Expanded priorities?
View 3 RepliesWeb Forms :: How To Handle Treeview Selected Node Changed Event
Sep 27, 2010I don't want to use Sessions to handle each click event inside treeview selected node changed.Secondly, if you suggest me to use treenode.SelectedValue then I would say my values are dyanmically generated.Everytime a node a clicked, the selected node value is sent in the next request xml to get response and xml schema is different for each click. How do I handle this each click event other than using session variables. I thought of using Request.Item (and integrating with URL redirect property) but I don't want to use that.

Web Forms :: Programmatically Fire Treeview Selectednode Changed From Gridview Rowcommand Event
May 27, 2010I have a treeview on the left panel and the gridview in the content page. Both the treeview and the gridview bind to the same datasource and have the same functionality. For instance, clicking employer in the treeview and clicking the employer link in the gridview take you to the same page. All I want is when I click the employer link in the gridview, I want the gridview row command event to call the selectednodechanged event of the treeview, so that the treenode for employer has the selected node style and performs the function of hte selectednodechanged. i have tried treeview.nodes[0].select but this does not fire the selectednodechanged event.
View 3 RepliesC# - TreeView Control Unexpected Event Behavior?
Apr 16, 2010In the MSDN is writen about TreeNode that:
"By default, a node is in selection mode."
"To put a node into selection mode, set the node's NavigateUrl property to an empty string."
"When a node is in selection mode, use the SelectAction property to specify which event or events are raised when a node is selected."
"Setting TreeNodeSelectAction value TreeNodeSelectAction.Select Raises the SelectedNodeChanged event when a node is selected."
Here is the problem and possibly a bug in the control:
When I set the TreeNode object PopulateOnDemand value to true and call the Collapse() function on that node.Then the TreeNodeExpanded event is raised in addition to the SelectedNodeChanged event.This is in complate contradiction to what is writen in the MSDN.According to the MSDN this sould happen only if TreeNodeSelectAction Property is set to TreeNodeSelectAction.SelectExpand value.
Here is the code:
<asp:TreeView ID="TreeView1" runat="server" AutoGenerateDataBindings="False"
onselectednodechanged="TreeView1_SelectedNodeChanged"
ontreenodepopulate="TreeView1_TreeNodePopulate"> [code]...

Web Forms :: Handling TreeView Error Detected By System.Web.UI.WebControls.TreeView.LoadPostData?
Mar 1, 2011Periodically 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.

View 1 RepliesWeb Forms :: Can Use UpdateProgress To Output Dynamic Text
Dec 20, 2010I'm working on a page which allows a user to do the following:
upload XML filevalidate XML filebulk loads data from XML file into MS SQL Server tablesruns a number of stored procedures to do certain checks on the imported data.
Now, I know how to do all of the above.
However, I would like to inform the user between the execution of the above mentioned actions what is happening.
I've looked at using the controls "updatepanels" and "updateprogress", but can't seem to get it to work.
If I put some static text like "Loading..." in the updateprogress control, I do see that whilst the code is running.
However, I don't want to show static text but want to change the text dynamically.
It appears that server-side controls are completely ignored inside the "updateprogress" control (why?).
Ideally I would like to do something like:
<form id="form1" runat="server">
<asp:ScriptManager ID="scriptMgr" runat="server" />
<div>
<asp:UpdateProgress runat="server" id="PageUpdateProgress">
<ProgressTemplate>
<asp:Label ID="Label1" runat="server" Text=""></asp:Label>
</ProgressTemplate>
</asp:UpdateProgress>
<asp:UpdatePanel runat="server" id="Panel">
<ContentTemplate>
<asp:Button runat="server" id="UpdateButton" onclick="UpdateButton_Click" text="Update" />
</ContentTemplate>
</asp:UpdatePanel>
</div>
</form>
In the code behind:
Protected Sub UpdateButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles UpdateButton.Click
Label1.Text = "Starting action 1."
System.Threading.Thread.Sleep(2000)
Label1.Text = "Starting action 2."
System.Threading.Thread.Sleep(2000)
Label1.Text = "Starting action 3."
System.Threading.Thread.Sleep(2000)
End Sub
Unfortunately I'm getting syntax errors on Label1.Text as it doesn't seem to recognize the control.
I know I'm a newbie and that I'm probably going around this completely the wrong way.
where I'm going wrong and how I can get this to work. I can't imagine I'm the only one who wants to achieve something like this in a webform.
