Hello
I am working on windows form application with c#.
I have used telerik radgrid on the form.
Need a checkbox in the radgrid cell depending on the value of the cell.
e.g. If the value in the cell is true or false then instead of showing true or false in the cell need to checkbox,
if the value in the cell is date or datetime then datetimepicker should display in the cell.
Here is the screenshot describing my problem.

Hi, Amol,
RadGridView provides a convenient API for specifying what editor to be activated. It is suitable to use the EditorRequired event. The following help article demonstrates a sample approach how to change the editor for a cell:
I hope this information helps. If you need any further assistance please don't hesitate to contact me.

Hello thanks for the reply, but sorry to say that it is not working.
Hi, Amol,
I have prepared a sample project for your reference. Please give it a try and see how it works on your end.
public RadForm1()
{
InitializeComponent();
GridViewTextBoxColumn gridViewTextBoxColumn1 = new GridViewTextBoxColumn();
GridViewTextBoxColumn gridViewTextBoxColumn2 = new GridViewTextBoxColumn();
gridViewTextBoxColumn1.HeaderText = "column1";
gridViewTextBoxColumn1.Name = "column1";
gridViewTextBoxColumn1.Width = 100;
gridViewTextBoxColumn2.HeaderText = "column2";
gridViewTextBoxColumn2.Name = "column2";
gridViewTextBoxColumn2.Width = 150;
this.radGridView1.MasterTemplate.Columns.AddRange(new GridViewDataColumn[]
{
gridViewTextBoxColumn1,
gridViewTextBoxColumn2
});
this.radGridView1.Rows.Add("row 1", DateTime.Now.ToString());
this.radGridView1.Rows.Add("row 2", "6");
this.radGridView1.Rows.Add("row 3", "test");
this.radGridView1.Rows.Add("row 4", true);
this.radGridView1.Rows.Add("row 5", false);
this.radGridView1.EditorRequired += radGridView1_EditorRequired;
this.radGridView1.CellEndEdit+=radGridView1_CellEndEdit;
}
private void radGridView1_CellEndEdit(object sender, GridViewCellEventArgs e)
{
if (e.ActiveEditor is RadCheckBoxEditor)
{
e.Row.Cells[e.Column.Name].Value = (ToggleState)e.ActiveEditor.Value == ToggleState.On ? "True" : "False";
}
}
void radGridView1_EditorRequired(object sender, EditorRequiredEventArgs e)
{
bool boolValue = false;
if (bool.TryParse(radGridView1.CurrentCell.Value.ToString(), out boolValue))
{
e.EditorType = typeof(RadCheckBoxEditor);
return;
}
}
The observed result is illustrated below:
Should you have further questions please let me know.

Hello Dess,
As you can see in the above image that when user clicks on the cell then it is showing the checkbox, but I want to show the checkbox without clicking on the cell(at the time of loading the data).
Hi, Amol,
If you don't want to enter edit mode and activate the editor at all, this means that you want to display different elements inside the cells belonging to the same column. The possible solution is to create one common cell element and add all the possible elements (RadButtonElement or LightVisualElement, etc.) that you will need to show in the visual cell. Then, you will need to manage the Visibility of each element considering your custom condition indicating which element to be shown for the row in the SetContentCore method of cell element.
A sample approach is demonstrated here:

Please give it a try and see how it would work for your scenario.
