Problems with Treeview control and button

Posted By:      Posted Date: October 27, 2010    Points: 0   Category :ASP.Net

I have a page with an ExtJS window and a asp:TreeView control and a asp:button inside it. When I click in the button, it doesn't fire the onclick event. When I change the UseSubmitBehavior property to false, it does fire the event, but the treeview CheckedNodes.Count is equal zero. I don't use (intentionally) any AJAX component in this page, so, why the onclick button doesn't work without "UseSubmitBehavior=false"? And why my CheckedNodes.Count is always zero? I have another simple page (without any complex javascript library) with the same treeview and button objects, and all controls works fine.

Having problems with the TreeView control.

I'm having problems with the TreeView Web Control.  What I am aiming to accomplish is to populate a TreeView control with my Active Directory information (similar to how it is structured in Active Directory Users and Computers) and when a node is selected, it's associated value is displayed in a text box.  I have the OnTreePopulate method and OnSelectedNodeChanged method implemented.  Each node has a name and value, which the value is the LDAP path I want displayed in the text box.  SelectAction = TreeNodeSelectAction and PopulateOnDemand =true.  Is there anything I'm missing? thanks, Pat

Problems with a .NET4 Control GAC Reference failing at runtime but fine during debugging

I believe this question is specific to the CLR how ever I will test this in a Forms Application later. I have multiple .Net 4 Targeted WPF Applications that Reference Non Microsoft .NET 4 WPF Controls that I can confirm are in the GAC. Everything Debugs Great (Noting that none of the references are copied to the output directory) and Install's well using a Setup Package and manually installing has the same effect even after a reboot. The problem is the application will not start even as an administrator as it does not find the Control References in the GAC. This also happens if I try to start the application manually in the visual studio output Directory. I can also confirm that opening the application in reflector that reflector is able to correctly find the references. Finally if I copy the controls (.dll's) to the location of the application everything runs as expected for all the above issues.   My question here is why is my application not able to load the .NET 4 controls from the GAC? Also note that everything uses a Strong Name.

I have a page where you can search and display other data, very simple layout. 1 Gridview and 1 objectdatasource. But i have 4 possible buttons that can populate the gridview.. i would like to control my objectdatasource from the code behind based on the button you click. here is what i have right now.. but if possible, can this source not be hardcoded like this and only built in the code behind? <asp:ObjectDataSource ID="ObjectDataSource1" runat="server" SelectMethod="SelectDVRInfo" TypeName="DataAccessCode"> <SelectParameters> <asp:ControlParameter ControlID="ddlDVR" Name="dvrInfo" PropertyName="SelectedValue" Type="String" /> </SelectParameters> </asp:ObjectDataSource> I found this site with a solution to this persons issue, but i cant seem to get mine working this way. http://stackoverflow.com/questions/2404264/overwriting-controlparameters-of-datasources-in-code-behind I have  this as the code behind right now when you press the button.. what other parameter settings am i missing and is this the right order to populate them for the source to acknowledge my values?   ObjectDataSource1.SelectMethod = "SelectDVRInfo"; ObjectDataSource1.SelectParameters["MyParameter"]
