Hi Shiva,

OnColumnResized event is fired after a column is resized. More information is available here:

In my application,in ItemDatabound event

protected void gvResourceTasks_ItemDataBound(object sender, GridItemEventArgs e)

{

string tasknamecellText = (e.Item as GridDataItem)["Task_Name"].Text;

//here ((int)clsGeneric.gridtooltip.task_name)=15

if (Convert.ToInt16(tasknamecellText.Length) > ((int)clsGeneric.gridtooltip.task_name))

{

(e.Item as GridDataItem)["Task_Name"].Text = tasknamecellText.Substring(0, (int)clsGeneric.gridtooltip.task_name);

string task_namelength = (e.Item as GridDataItem)["Task_Name"].Text;

if (Convert.ToInt16(task_namelength.Length) == (int)clsGeneric.gridtooltip.task_name)

{

//string length1 = length + "......";

 (e.Item as GridDataItem)["Task_Name"].Text = task_namelength +"......";

        //(e.Item as GridDataItem)["Description"].Text = length1;

}

}

}

So,when I resize taskname column,entire text not displaying.

When I am resizing,the total text has to be displayed.

In function columnresized(sender,eventargs),how I have to write?

Hello , 

I know this is  a very old post .But exactly  I have to do the same. 

 (item[col.UniqueName] as TableCell).ToolTip = item[col.UniqueName].Text;

                                item[col.UniqueName].Text = item[col.UniqueName].Text.Substring(0, 29) + "...";

now in the ClientEvents.OnColumnResizing event I want to show the full text ( when the Column size is larger and apply the sub string again Column size is shorter dynamically with .... ) 

Anyone can help me please

Thanks 

Sanjukta

Hi Sanjukta,

As we already have reached to a working option in the support thread you have opened I will post the suggested solution here as well:

Assigning a Substring of the original value to the Cell text will replace the initial string in the cell and therefore it cannot be recovered when enlarging the column width.

I would suggest avoiding the text modification inside the cells and use custom CSS to achieve the desired appearance.

Sample CSS:

html body .RadGrid tbody > tr.rgRow > td,
html body .RadGrid tbody > tr.rgAltRow > td {
    white-space: nowrap;
    overflow: hidden;
    text-overflow: ellipsis;
}

Find more about the used CSS properties below:

• CSS text-overflow Property
• CSS overflow Property
• CSS white-space Property

Thank you so much. it was a great help. 

Is there any way I can show tooltip when the ellipsis is activated ? Only for those RadGrid Column cell where Ellipsis ( .... ) there 

 

 

Thanks

Hi Sanjukta,

I have sent an answer to your question in the support ticket you have opened on the same topic.

I would suggest you proceed with the communication there only. Once we reach the resolution I will post it in this forum so that it is visible to others facing the same problem.

Sanjukta,

As I intended, I am sharing the proposed approach for achieving the desired behavior using RadToolTipManager.

1. Declare a RadToolTipManager with enabled AutoTooltipify and wire up the OnClientBeforeShow event listener:
   

   <telerik:RadToolTipManager ID="RadToolTipManager1" runat="server" AutoTooltipify="true" OnClientBeforeShow="onClientBeforeShow"></telerik:RadToolTipManager>

2. In the event listener, check if the text inside the target control is wrapped by comparing the offsetWidth and scrollWidth (in the current scenario target is the Grid cell <td> element). If text is wrapped, cancel the event:
   

   function onClientBeforeShow(sender, args) {
       var target = sender.get_targetControl();
       if (target.offsetWidth >= target.scrollWidth) {
           args.set_cancel(true);
       }
   }
