I've went through the 3 steps here:

http://www.telerik.com/support/kb/article/b454K-eda-b454T-kb-b454c-kb.aspx

Still, I get a permission denied error when I try to modify or delete any files using the treeview. I have it working in other scenarios, but I think my permissions may be fouled up, or I'm overlooking something. The full error is:

[Solved] onchange event for input element

Hi. I have a problem with handling onchange event in input element of RadComboBox. My custom combobox control derived from RadComboBox and overrides OnLoad server event:

protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
this.Page.ClientScript.RegisterStartupScript(this.GetType(),"blabla","$get('"+ this.ClientID + "_Input').onchange=\"AfterUpdate('" + this.ClientID + "')\";",true);
}

In resulted html I see:

<INPUT class="rcbInput" id="ctl00_hldrMain_ctl00_cmbDirectors_Input" style="DISPLAY: block" onchange="AfterUpdate('ctl00_hldrMain_ctl00_cmbDirectors')" name="ctl00$hldrMain$ctl00$cmbDirectors_Input" autocomplete="off" value="" />

onchange present but does not work. Please help.

[Solved] Checkbox CheckedChanged event in GridTemplateColumn

Hi Guys,

I am having a hard time putting an asp:CheckBox control inside of a GridTemplateColumn and subscribing to the CheckedChanged event for it... The checkbox posts back when I click on it, but the event never gets fired...

Here's the code:

    
            <telerik:RadGrid ID="rgPublicFields" runat="server" Skin="Vista"> 
        
                <MasterTableView AutoGenerateColumns="false"> 
        
                    <Columns> 
        
                        <telerik:GridBoundColumn UniqueName="PublicFieldID" DataField="PublicFieldID" Visible="false"></telerik:GridBoundColumn> 
        
                        <telerik:GridTemplateColumn HeaderText="Include" UniqueName="Active"> 
        
                            <ItemTemplate> 
        
                                <asp:CheckBox ID="cbInclude" runat="server" Checked='<%# System.Convert.ToBoolean(int.Parse(Eval("Active").ToString())) %>' Text='<%# Eval("PublicFieldID") %>' AutoPostBack="true" OnCheckedChanged="cbInclude_CheckedChanged" /> 
        
                            </ItemTemplate> 
        
                        </telerik:GridTemplateColumn> 
        
                        <telerik:GridBoundColumn HeaderText="Field Name" UniqueName="FieldName" DataField="FieldName"></telerik:GridBoundColumn> 
        
                        <telerik:GridTemplateColumn HeaderText="Display As" UniqueName="DisplayName"> 
        
                            <ItemTemplate> 
        
                                <asp:TextBox ID="tbDisplayName" runat="server" Text='<%# Eval("DisplayName") %>'></asp:TextBox> 
        
                                <asp:Button ID="btnUpdate" runat="server" CommandName="UpdateDisplayName" CommandArgument="" Text="Update" /> 
        
                            </ItemTemplate> 
        
                        </telerik:GridTemplateColumn> 
        
                    </Columns> 
        
                </MasterTableView> 
        
            </telerik:RadGrid>

And the codebehind:

    
                    protected void Page_Load(object sender, EventArgs e) 
        
                    { 
        
                        DataSet ds = new DataSet(); 
        
                        ds.Tables.Add(); 
        
                        ds.Tables[0].Columns.Add("PublicFieldID"); 
        
                        ds.Tables[0].Columns.Add("Active"); 
        
                        ds.Tables[0].Columns.Add("FieldName"); 
        
                        ds.Tables[0].Columns.Add("DisplayName"); 
        
                        ds.Tables[0].Rows.Add(new object[] { 1, 1, "Email", "Email Address" }); 
        
                        rgPublicFields.DataSource = ds; 
        
                        rgPublicFields.DataBind(); 
        
                    } 
        
                    protected void cbInclude_CheckedChanged(object sender, EventArgs e) 
        
                    { 
        
                        CheckBox cb = (CheckBox)sender; // I have a breakpoint set here that never stops 
        
                    }

If anyone could help me identify why this is happening, it would be greatly appreciated.

I am trying to implement a CardView Grid Programmaticly using an ITemplate and OnDemand Datasourcing and run into an error telling me that the datasource is null when I try to expand a detail table.

How do I create a client template from the code-behind?

I can't seem to figure this out.

I have a Grid with a GridCheckBoxColumn. It is bound to a Boolean field in a table.

I've enabled the checkbox in the ItemDataBound event.

The Grid has paging turned on.

When a user selects a checkbox, and moves to the next page. How do I get the values from the row that was checked?

I tried using the ItemEvent event and went so far as to iterate through all the items, but it only tells me the original status of the checkbox field. It doesn't tell me that the user changed a checkbox.

How do I find this? I've been reading tons of documentation, but I can't seem to find what I'm after.

Thanks
Kevin

I am running into this issue which I am unable to resolve. Within an aspx page (that uses a master page), I have a slider control (Test1). The page is initially presented with Test1. But once it is undocked (Test1 moves up and hides), clicking on Test1 doesn't display it again.

Please help. I have provided the code below.

RadMenu + ExtJS BorderLayout = RadMenu dropdowns hidden behind top panel

I am using ExtJS's ViewPort and putting a RadMenu into the North region (header). Dropdown menus are hidden behind the panel the RadMenu is in. Is there a way to fix this? Is RadMenu rendered with absolute positioning? I tried setting the z-index but doesn't seem to work.

Problem with GridFilter's Dropdownlist

EDIT: This has been solved by adding:

<link href="Skins/Office2007/Menu.Office2007.css" rel="stylesheet" type="text/css" />

When I click the filter icon on my grid, the menu pops up and I see a list of items, but there is no background to the menu.

My grid has EnableEmbeddedSkins set to "false". Whenever I set it to "true" it works, so the problem has something to do with that.

I am using the Office2007 skin, and I have all of the Office2007 images and the Office2007 CSS file inside the correct directory:

mySite/Skins/Office2007/

Thanks for your help.

rebind() doesn't work, but refresh button does

I've created the grid on runtime with code below in an acsx file. whenever I am inserting a new record it will recognize the new record being inserted but the grid will not update the database.

But everytime I click the refresh button on the commandline it actually refreshes my grid with the updated data.

Rebind() does not work if you bind your datasource manually, my company does not allow any drag and drop datasources.
