When the user click "Add new row", I need to disable it

[rema43001]

Hello:
When the user click "Add new row", I need to disable it,
for example,
if the user click on "Add New Row" the program execute a routine that return a boolean,
if the routine return true then "Add new row" must to display a message "You can't add more rows".
And the inputs for insert don't must appear.

Can you help me?

Thanks.

You could try the following piece of code after the boolean is returned:

GridCommandItem myItem = (GridCommandItem)RadGrid1.MasterTableView.GetItems(GridItemType.CommandItem)[0];
((LinkButton)myItem.FindControl("InitInsertButton")).Visible = false;

To disable that particular button. You could then perhaps take use of a RadAlert or another RadWindow to display your error message.

Thanks Schlurk

It's possible to acces the EditButton?

GridCommandItem myItem = (GridCommandItem)RadGrid1.MasterTableView.GetItems(GridItemType.CommandItem)[0];  
((LinkButton)myItem.FindControl("EditButton")).Visible = false;

this return the error {"Object reference not set to an instance of an object."}
Can you help me?

Thanks

Hello,

I hope you want  to hide the autogenerated EditButton in the grid from code behind. If so you can try following code in ItemDataBound event.

CS:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {
        GridDataItem myItem = (GridDataItem)e.Item;
        ((LinkButton)myItem.FindControl("AutoGeneratedEditButton")).Visible = false;
    }
}

-Shinu.

Thanks Schlurk, for the code hide the InitInsertButton

GridCommandItem myItem = (GridCommandItem)RadGrid1.MasterTableView.GetItems(GridItemType.CommandItem)[0];  
((LinkButton)myItem.FindControl("InitInsertButton")).Visible = false; 

But is necessary to hide the Image next to "Add new row" that have the same function.

Anyone know how to hide this?

Thanks.
