jyotsna asked on 18 Mar 2016, 02:21 PM

I am trying to open the Raddataform which is in Editform control of Rad Grid in the insert mode ,and as there are no items in the grid it goes to exception as above users,I tried the solution from Ole like inserting an empty template but dint work out. when I have data in the grid it works fine for the new grid to add a record using the dataform it fails.pls suggest.Here is sample.

I also Tried All options mentioned in the other Threads

// gridDataform.DataForm.IsItemInserted = true;
// gridDataform.DataForm.Rebind();
// gridDataform.DataForm.Items[0].FireCommandEvent("InitInsert", "");
gridDataform.DataForm.ShowInsertItem();

gridDataform is the instance of the usercontrol which has Raddataform and this code is beign used in the grid itemcommand.

if (gridDataform == null)
{ throw new Exception("No Grid Found"); }

log.logDebug(logMessage: "Fire Insert Mode for DataForm");

gridDataform.DataForm.Items[0].FireCommandEvent("InitInsert", "");
Also my add buttons are on the mastertableview of the grid

<MasterTableView Width="100%" CommandItemDisplay="Top" ShowGroupFooter="true" AllowFilteringByColumn="true">
<EditFormSettings EditFormType="Template">
<EditColumn UniqueName="EditCommandColumn1" />
<FormTemplate>
<uc1:PageUIControl IsBoundToGrid="true" runat="server" ID="EditFormControl" />
</FormTemplate>
<PopUpSettings ScrollBars="None" />
</EditFormSettings>

<CommandItemTemplate>

<div style="color:black!important;" >

<asp:LinkButton ID="btnEditSelected" runat="server" CommandName="EditSelected" Visible='<%# RadGridUI.EditIndexes.Count == 0 %>'><i class="fa fa-pencil fa-lg"></i></asp:LinkButton>
<asp:LinkButton ID="btnUpdateEdited" runat="server" CommandName="UpdateEdited" Visible='<%# RadGridUI.EditIndexes.Count > 0 %>'><i class="fa fa-pencil fa-lg"></i></asp:LinkButton>

and the code where the raddataform is called in insert mode from grids itemcommand.:I tried all the ways in the below commented code:

if (insertedItem == null)
{ throw new Exception("No Inserted Item Found"); }

gridDataform.UpdateMode = PageUIControl.Mode.Insert;
gridDataform.UserContext = this.UserContext;
gridDataform.UserID = this.UserID;
//String MyUserControlId = GridEditFormItem.EditFormUserControlID;
// gridDataform = insertedItem.FindControl(MyUserControlId) as PageUIControl;

if (gridDataform == null)
{ throw new Exception("No Grid Found"); }

log.logDebug(logMessage: "Fire Insert Mode for DataForm");

// gridDataform.DataForm.IsItemInserted = true;
// gridDataform.DataForm.Rebind();
gridDataform.DataForm.Items[0].FireCommandEvent("InitInsert", "");
// gridDataform.DataForm.ShowInsertItem();
//gridDataform.DataForm.DataSource=RadDataFormEmptyItem
// gridDataform.DataForm.Items.FireCommandEvent("InitInsert", "");
// gridDataform.DataForm.Items[0].FireCommandEvent("InitInsert", "");
// gridDataform.DataForm.Items.Add();
}
else if (e.CommandName == "RowClick")
if (ItemCommand !=null)
{ ItemCommand(sender, e); }


}
catch (Exception ex)
{
log.logError(logMessage: "RadGridUI_ItemCommand Error: " + ex.Message );

((TextBox)TableUIErrorNotification.ContentContainer.FindControl("txtnot")).Text = log.logstr;
TableUIErrorNotification.Show();
}
finally
{
log.logDebug(logMessage: "RadGridUI_ItemCommand Exit ");
log.Flush(logger: "RadGridUI_ItemCommand");
}

}

I am also attaching the screen shot for better understanding of how the ui looks with the raddataform which opens with the above working code if there is data in grid.
