Hello Shankar,

To implement the desired functionality I recommend that you set the ReadOnly property of the textboxes you want to make non-editable to true. You can find them in the Controls collection of the corresponding column editor.

I hope this helps.

hello mira

if i set the read only property true then  the control disaapears, i wanna make the control as non editable{disabled}

foreach

 

(GridColumn column in RadGrid1.MasterTableView.RenderColumns)

 

{

.........................

if

 

(column.UniqueName == "b")

 

{

(editor

as GridTextColumnEditor).Text = "Done";

 

(column

as GridBoundColumn). readonly=true;

 

}

-----------------
i dont wanna use template controls ,cos i ve 50 columns so it takes much time to load,when i select value from drop down inside the grid it takes around 14 to 15 secs to load,

Hello Shankar,

I suggest that you try using the following code to implement the desired functionality:


((editor as GridTextColumnEditor).Controls[0] as TextBox).ReadOnly = true;

Please let me know whether it helps.

hello mira

((editor

as GridTextColumnEditor).Controls[0] as RadTextBox).ReadOnly = true;

 

am getting err when i use the above code

""Specified argument was out of the range of valid values. Parameter name: index""

ok i ll use template controls for this but it takes much time to load,is their any possibilities to bind at client side

need client side event for dropdown template controls{rad:dropdown}   selected index changed event to bind values for template control{rad:textbox}

anyways thaks for the reply,
if possible reply for the above post else no probs
