Unable to add CheckBox to First Column in GDBGTreeLines Grid

[Raul]

Hi,

I would like to add a checkbox to the first column in GDGBG Tree lines Grid.
I am appending a small dummy sample in which I was trying add a checkbox to the first column.
Checkbox will work for any column index except the first one.

Thanks,

Hi Raul,

Thank you for your interest in Syncfusion products.

To Solve this issue You need to handle QueryCellInfo event to set the CellType of the first column as checkbox and QueryColWidth to set the width of the first column. Please refer the code below for more details.

  void Model_QueryColWidth(object sender, GridRowColSizeEventArgs e)
  {
   if (e.Index == 1)
   {
    e.Handled = true;
    e.Size = 20;
    }
   }

   void dgrd_PrepareViewStyleInfo(object sender, GridPrepareViewStyleInfoEventArgs e)
   {
    if (e.ColIndex == 1)
    {
     Console.WriteLine(e.Style.CellType);
     e.Style.CellType = "CheckBox";
     e.Style.CellValue = true;
     }

   }

Here is the modified sample that implements this task.

I tried using the code appended by you...still I do not get the desrired checkbox in the first column.

Also I downloaded the web samples (SyncGrid.zip) that was appended, that too didn;t contain the checkbox in the first column.

Hi,

Now the checkBox column shows, however

1> The one highlighted in red, does not check , uncheck upon clicking it.

2>The other checkbox column thorws an exception "Column 'Key" is constrained to be unique. Value 'True" is already Present" when I try to check all the three columns.

Now yr sample does not show any checkbox only...and also on clicking on the Plus (collapsed) sign...the sign remains Plus.

Kindly verify the results before posting it.
