Hi There,

ContextMenuItemClick server side event returns e.Node as null all the time. Certainly I am missing something here but not sure what,

The code is as below.

<

telerik:RadTreeView ID="CategoryTree"

Runat="server"

Skin="Windows7"

DataSourceID="SqlDataSource1"

CheckBoxes="True"

MultipleSelect="True"

DataFieldID="CategoryId"

DataFieldParentID="ParentID"

DataTextField="CategoryName"

DataValueField="Category"

OnNodeDataBound="CategoryTree_OnNodeDataBound"

OnContextMenuItemClick="CategoryTree_ContextMenuItemClick"

OnClientContextMenuShowing="onClientContextMenuShowing"

OnClientContextMenuItemClicking="onClientContextMenuItemClicking"

TriStateCheckBoxes="False"
AllowNodeEditing="True">

<telerik:RadTreeViewContextMenu ID="MyContextMenu" runat="server" Skin="Windows7" >

<Items>

<telerik:RadMenuItem runat="server" ImageUrl="~/Images/add.gif" Text="Add new category" Value="New">

</telerik:RadMenuItem>

<telerik:RadMenuItem runat="server" ImageUrl="~/Images/edit.gif" Text="Edit category" Value="Edit">

</telerik:RadMenuItem>

<telerik:RadMenuItem runat="server" ImageUrl="~/Images/delete.gif" Text="Delete category" Value="Delete">

</telerik:RadMenuItem>

</Items>

</telerik:RadTreeViewContextMenu>

</ContextMenus>

<telerik:RadTreeNodeBinding Expanded="True" ContextMenuID="MyContextMenu"/>

</DataBindings>

</telerik:RadTreeView>

protected void CategoryTree_ContextMenuItemClick(object sender, RadTreeViewContextMenuEventArgs e)

{

if (e.Node != null)

{

        //check for menuitem text
    }
    else
    {
        return;
    }
}

e.Node is always null, Could someone please advise me why am I getting e.Node as null everytime inside the ContextMenuItemClick event.

Achieving a Darker Background for Modal RadWindows

I've read everything I could find about altering the darkness of the "filter" that is applied behind a modal RadWindow. I've tried several things based on that research but with no success. Simply put, what I'm getting is shown in the first attachment but what I'd like to achieve is illustrated in the 2nd attachment (the one wrt 'thickbox').

Here's the CSS styles I've been using:

.modalBackgroundRadWindow {
filter:Alpha(Opacity=95);          /* IE7 and under */
-ms-filter: "Alpha(Opacity=95)";   /* IE8 */
   -moz-opacity: 0.95;
   opacity: 0.95;
}

.modalBackgroundThickBox {
   background-color:#000;
   filter:alpha(opacity=75);
   -moz-opacity: 0.75;
   opacity: 0.75;
}

What do I need to do with the RadWindow to achieve a darker background filter?

Reading formatted grid bound columns

I have gridbound column Col_A and COL_B and dataformat set to currency.Both these columns are integer . I have embeded udpate statement in sqldatasource to update both these columns. Based on business rule I open only one column for editing before update.

If COL B is open for update(COL A is read only in this scenario), When I execute update statement COL A is reading the formatted value and passing to SQL staement i.e formatted currency value and this gives database error because COL A is integer type.
1) How can i get the just the value of COL A (not the formmated one for example , I need 3000 not 3,000). Extravalues in edit mode not working
2) How do i put mask for editable column ,i.e the user can type 5,000 rather than 5000 , but the value read is 5000

Thanks

Filters dont persist on page change?

So i drop down the filter boxes and initiate a filter for Starts With B. I get 25 Results (set to 10 per page). If I go to page 2 then back to page 1 the filter is no longer applied.

What is the recommended way to have filter settings persist across page changes?

Thanks,
Michael

Expand\Collapse Columns

Hi,

Is there any functionality for columns, similar to the DetailTables for rows, which will allow me to group columns together and through a button press expand\collapse them?

My client has an Excel spreadsheet with 20 columns in it and they want me to replicate the funcationality they have, displaying all the data. I've told them that it'd be too wide for the screen, so they've asked if they can expand\collapse sections of the data (I can logically split it in to 4 separate sections).

Thanks in advance for your help.

Value of cell always "&nbsp" on OnItemCreated

Hi,

I bind my grid programmatically during the NeedDataSource event which is in turn a SQLDataSource instance:

protected void grdMyGrid_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

{

((RadGrid)sender).DataSource = sqlDs;

}

From here I’m trying to check if the value of a specific cell match a condition during the ItemCreated event:

protected void grdMyGrid_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)

{

if (e.Item is GridDataItem)

{

var item = e.Item as GridDataItem;

if (item["ValidationState"].Text == "UNMATCHED")

{

item.BackColor = System.Drawing.Color.Red;

item.ForeColor = System.Drawing.Color.White;

}

For some reason the value of item[“ValidationState”].Text is always "&nbsp" as so is any other cell I’m trying to access via the UniqueName property. And yes, they are explicitly defined in my markup of the columns.

It is maybe becuase I bind the grid during NeedDataSource and not at design time with the DataSourceID property specified? Or perhaps other suggestion or solutions?

Thanks for you help!
