[Solved] How to set the default value to checkced when inplace editing a GridCheckboxColumn

[Jonathan]

How do I set the default value to checked when inplace editing a GridCheckboxColumn?  Is this possible or would I have to use a template column with a checkbox set to checked?  Also are there any examples of using a dropdownlistcolumn?

Hi Jonathan,

Try the following code snippet to set the value of the CheckBox column to be Checked in edit mode.

ASPX:

     <telerik:GridCheckBoxColumn DataField="Passed" DataType="System.Boolean" HeaderText="Passed"
                        SortExpression="Passed" UniqueName="Passed">
                    </telerik:GridCheckBoxColumn>

CS:

 protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if ((e.Item is GridEditableItem) && (e.Item.IsInEditMode))
        {
            GridEditableItem edititem = (GridEditableItem)e.Item;
            CheckBox chkbx = (CheckBox)edititem["Passed"].Controls[0];
            chkbx.Checked = true;
        }
    }

Refer the following help article to get details on configuring a GridDropDownColumn.

Thanks Shinu,

I should be more specific.. I only want the default value to be set when inserting a new item.  When editing an item it will be set based on the datasource of the bound item.  Will your solution take this scenario into account?

Hello Jonathan,

If you want to set the default value of the checkbox column in InsertMode only then try the following code.
cs:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if ((e.Item is GridEditFormInsertItem) && (e.Item.OwnerTableView.IsItemInserted))
        {
            GridEditFormInsertItem edititem = (GridEditFormInsertItem)e.Item;
            CheckBox chkbx = (CheckBox)edititem["Passed"].Controls[0];
            chkbx.Checked = true;
        }
    }

Thanks
Princy.

Hi Princy.

I am using in-place editing and inserting not using an edit form. 

        if ((e.Item is GridEditFormInsertItem) && (e.Item.OwnerTableView.IsItemInserted))
        {

never evaluates to true when entering insert mode.

ANy thoughts.

Cheers
Jonathan

OK this works:

   protected void radGridLookups_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)
   {
       if (e.Item is GridEditableItem && e.Item.IsInEditMode)
       {
           if (e.Item.OwnerTableView.IsItemInserted)
           {
               GridEditableItem edititem = (GridEditableItem)e.Item;
               CheckBox chkbx = (CheckBox)edititem["Active"].Controls[0];
               chkbx.Checked = true;
           }
       }
   }
