Hi Santaji,

Set the FieldName of the column which is not visible as the DataKeyNames in the aspx and Try the following code snippet to achieve the desired scenario.

ASPX:
                 <DetailTables> 
                      <telerik:GridTableView runat="server"   Name="Detail" DataKeyNames="CheckCol1,CheckCol2"  DataSourceID="SqlDataSource2" > 
                       <Columns> 
                         <telerik:GridBoundColumn DataField="ValueCol" HeaderText="ValueCol" SortExpression="ValueCol" 
                            UniqueName="ValueCol" ></telerik:GridBoundColumn> 
                         <telerik:GridBoundColumn DataField="CheckCol1" HeaderText="CheckCol1"  Visible="false" SortExpression="CheckCol1" 
                            UniqueName="CheckCol1" ></telerik:GridBoundColumn> 
                         <telerik:GridBoundColumn  DataField="CheckCol2" HeaderText="CheckCol2"  Visible="false" SortExpression="CheckCol2" 
                            UniqueName="CheckCol2"  ></telerik:GridBoundColumn> 
                            <telerik:GridEditCommandColumn></telerik:GridEditCommandColumn> 
                       </Columns> 
                      </telerik:GridTableView> 
                     </DetailTables> 


CS:
 protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e) 
    { 
        if ((e.Item is GridDataItem) && (e.Item.OwnerTableView.Name == "Detail")) 
        { 
            GridDataItem item = (GridDataItem)e.Item; 
            string strKey1 = item.GetDataKeyValue("CheckCol1").ToString(); 
            string strKey2 = item.GetDataKeyValue("CheckCol2").ToString(); 
            if ((strKey1 == "True") && (strKey2 == "True")) 
            { 
                item.Edit = true
            } 
        } 
   } 


Thanks
Princy.

I have a similar requirement, but it differs in that editing is "InPlace", and based upon a row-level data condition, certain fields will be read-only, while the rest of the row remains editable.

ex:

Col1     Col2     Col3     Col4
-------------------------------------
1         open     edit       edit
2         locked   edit       read-only
3         open     edit       edit
4         locked   edit       read-only

Is there a way to achieve this with server side code in ItemCreated or ItemDataBound?

Thanks,
Brent

Hi Brent,

Try setting 'COl2' as the DataKeyName and then in the ItemCreated event you may try the following code logic to achieve the desired scenario.

CS:
 
protected void RadGrid2_ItemCreated(object sender, GridItemEventArgs e) 
    { 
        if ((e.Item is GridEditableItem) && (e.Item.IsInEditMode)) 
        { 
            GridEditableItem item = (GridEditableItem)e.Item; 
            string strCondition = item.GetDataKeyValue("Col2").ToString(); 
 
            if (strCondition == "locked"
            { 
                TextBox txtbx = (TextBox)item["Col4"].Controls[0]; 
                txtbx.Visible = false
            } 
 
        } 
    } 


Best Regards
Princy
