Using context menu on grid to update data

Hello,

Is there a way to have a template column with a linkbutton containing a pop-up context menu, allowing to update the data on that row? I have a grid populated with data (from the NeedDatasource handler). I'd like to allow user to left-click on the link button to pop-up a menu, and select a menu item which will update the underline record's data according to the menu item's value. I couldn't find any message/knowledge base to allow me to pass the datakey's value from the client to server to pass on to the DAL. I want to use left-click on a linkbutton to restrict users only to click on the button to activate the allowable command (and also, make it more user-friendly!)

Since I don't know where to start, it'd be tough to provide some code. Any help would be greatly appreciated.

Tri.

Spell check for grid

We tried to check the spelling for data item inside Grid.
How do we fire up spelling control when we click update button of grid?
Here is the following code modified from your example:

GridEditableItem editedItem = (e.Item as GridEditableItem);

LinkButton actionButton;

//insert mode

if (editedItem.OwnerTableView.IsItemInserted)

{

actionButton = editedItem.FindControl("PerformInsertButton") as LinkButton;

}

//edit mode

else

{

actionButton = editedItem.FindControl("UpdateButton") as LinkButton;

}

actionButton.OnClientClick = "return StartCheck();";

HiddenField1.Value = actionButton.ClientID;

IGridColumnEditor editor = editedItem.EditManager.GetColumnEditor("Comment");

string editorID = editor.ContainerControl.Controls[1].ClientID;

RadSpell1.ControlsToCheck = new string[1] { editorID };

RadSpell1.IsClientID = true;

Changes to CSS File Changes Not Loaded after Postback

My Scenario:

Single web page with TabStrip and MultiPage. Tab1/Page1 has a RadEditor that is used by the user to enter html. Tab2/Page2 has an editor that allows the user to create a stylesheet. When the user switches from Tab2, server side the users styles are written out to a file. The CSSFiles in the RadEditor are cleared and the newly created CSSFile is added to the editor. This works and the "Apply Styles Class" gets the styles in the drop down.

After going back to Tab 2 and making changes to the style sheet, when the user switches back to Tab 1, the new styles are applied to the file and the file is again removed and added to CSSFiles (Same File name). Even though the file has changed, the RadEditor is using the contents from the previous version of the file.

So, I am pretty sure that the file does not get loaded again, because of caching by the browser. I don't think this is an issue with the RadEditor itself.

So my question is, "Is there a way to force the css to reload on these subsequent changes to pickup the changes to the CSS file?"

Trigger Linkbutton automatically once grid is loaded

I have a RadGrid. It contains multiple controls inside of it. One of them is a linkbutton whose clientClick triggers window.open. After the grid is loaded, I want to trigger the linkbutton's click if and only if the grid contains only one item.

I am defining the grid as follows:

<rad:RadGrid ID="rg" runat="server">

<ClientSettings>

<ClientEvents OnDataBound="rg_DataBound" />

</ClientSettings>

<MasterTableView PageSize="50" DataSourceID="ods" DataKeyNames="Id">

<rad:GridTemplateColumn HeaderText="Name" SortExpression="a.Name">

<ItemTemplate>

<asp:LinkButton ID="lblName" runat="server" />

</ItemTemplate>

</rad:GridTemplateColumn>

</MasterTableView>

</rad:RadGrid>

In my codebehind, I am definining the ClientClick at the ItemCreated method.

var lb = (LinkButton)e.Item.FindControl("lbName");

lb.OnClientClick = "window.open('NewPage.aspx?id=" + obj.Id + "'); return false;";

I implemented the client grid databound as follows:

function rg_DataBound(sender, e) {

var masterTable = $find('<%= rg.ClientID %>').get_masterTableView;

var dataItems = masterTable.get_dataItems();

if (masterTable.get_pageCount() == 1 && dataItems.get_count() == 1) {

var lb = dataItems[0].findControl('lbName');

lb.click();

}

But this javascript method does not even get fired. Basically I have two questions at this time:
1. Am I in the right track?
2. Why is rg_DataBound not firing?

Thanks.
