[Solved] Why does this demo using Response.ApplyAppPathModifier(Request.Url.PathAndQuery)?

Hi,
I am considering which approach should I use to make a menu navigation bar - sitemapdatasource or using the query string.
My menu bar is dynamically generating menu base on row data in my database table.
This demo is using Response.ApplyAppPathModifier(Request.Url.PathAndQuery) but I have seen there is an action to change those tabs.

Dim tab As RadTab = RadTabStrip1.FindTabByUrl(urlWithSessionID)

If Not IsNothing(tab) Then

   tab.SelectParents()

   tab.PageView.Selected = True

End If

so why do we need Response.ApplyAppPathModifier(Request.Url.PathAndQuery) here? I hope this will also help me develop my dynamically generating menu bar. Thx!

OnClientClick event is getting fired for <asp:ImageButton>

Hi,

I have asp imagebutton in my page. By default i am loading disabled image. and have set the property of Enabled = false in the page. On Change of any field value in the page i am making the disabled image as enabled as below. After this if I click on Enabled image it is not firing OnCLientClick javascript method. Why? Any body please help me.

On load of the Screen

<asp:ImageButton ID="imgbtnOk" runat="server" ImageUrl="~/Images/btn_ok_disabled.gif"

OnClientClick="return ValidateInformation()" AccessKey="O" ToolTip="OK" TabIndex="30" />

On updatation of any field in the screen following javascript has been fired to enable the button

//Enables the Ok button if user selects any Carrier Plan Code

function EnableOk() {

var cboCarrierPlanCode = document.getElementById(radcboCarrierPlanCode)

if (cboCarrierPlanCode.value != "") {

var updateflag = document.getElementById(hdnChangeFlag)

updateflag.value = 1;

var imgBtnOk = document.getElementById(imgbtnOk)

imgBtnOk.disabled =

false

imgBtnOk.src =

"../Images/btn_OK.gif"

}

}

After this image is getting enabled but initially for the control i have written OnClientClick event to validate some more fields in the screen.... this is not getting fired.

WHY?

Sorting on GridImageColumn

Hi,
I have a grid, that has a GridImageColumn. The imageUrl is working correctly, and on ItemDataBound I Clear the image out from some rows, so I am left with a grid that has some rows with an image and some without in the same column. My question is simply, is there a way to sort on that column?? I tried adding an invisible GridBoundColumn which I would populate with either a "1" or a "0" and set my sort expression to that column and set AllowSorting to true, but when I click on the column header I receive an error that says Cannot find column, so I think that's the wrong approach. See code below.

Any help will be greatly appreciated.

Thanks,

-Mike

Following is the code i am using for update panel

<telerik:RadAjaxManagerProxy ID="radAjaxMgr" runat="server">

<telerik:AjaxSetting AjaxControlID="rgrdDocumentList">
<UpdatedControls>
<telerik:AjaxUpdatedControl LoadingPanelID="lstLoadingpane" ControlID="rgrdDocumentList" />
<telerik:AjaxUpdatedControl ControlID="hiddenDirtyFlag" />
</UpdatedControls>
</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManagerProxy>

<telerik:RadAjaxLoadingPanel Transparency="10" ID="lstLoadingpane" runat="server"
IsSticky="true" CssClass="FileStoreModalPanel">

White space above scrollbar on radgrid

I have set my radgrid header color to gray and I am not using a skin. The problem is that I have a white box in the upper right corner of the grid above the scrollbar. If I increase the width of my header to fill the space then I get a scroll bar at the bottom of the grid and the white box just gets pushed to the right. How can i color this space without coloring the entire grid? I have attached a file showing the area I am trying color.

Populate ComboBox inside FormTemplate

I would like to populate the combo boxes on my edit FormTemplate on Page_Load. Is this possible or do I have to do it on item created event? I would like to do it once versus re-populating the control every time the user clicks "edit".

Thanks
Scott
