[Solved] How to turn off grid insert mode

[arboboo]

I want to attach a right context menu to a RadGrid .  I followed the instruction in the article:

http://www.telerik.com/demos/aspnet/controls/Examples/Integration/GridAndMenu/DefaultCS.aspx?product=grid

 

As my data source is a collection, I have to handle the RadGrid1_InsertCommand to insert the new record into database.

But after update database, how can I turn off the grid insert mode? I put

RadGrid1.MasterTableView.IsItemInserted = false; in the RadGrid1_InsertCommand, but I received a exception:

Insert item is available only when grid is in insert mode.

 

 

protected void RadGrid1_InsertCommand(object source, GridCommandEventArgs e)

{

GridEditableItem editedItem = e.Item as GridEditableItem;           

      

      // get sort order

      RadNumericTextBox txtSortOrder =

      editedItem.FindControl("RadNumericTextBox_SortOrder") as RadNumericTextBox;

      int sortOrder = -1;

      Int32.TryParse(txtSortOrder.ValidationText, out sortOrder);

 

      // InsertIntoDatabase()

      …

     

 

      //exception: Insert item is available only when grid is in insert mode.

      RadGrid1.MasterTableView.IsItemInserted = false; 

        

}

 

 

protected void RadGrid1_UpdateCommand(object source, GridCommandEventArgs e)

{

   GridEditableItem editedItem = e.Item as GridEditableItem;

 

   // get category Id

   Label lblId = editedItem.FindControl("lblId") as Label;           

   int categoryId = 0;

   Int32.TryParse(lblId.Text, out categoryId);

   if (0 == categoryId) return;

        

   // update database

…

 

     

   //works fine

    RadGrid_Categories.EditIndexes.Clear();

  

   

}

 

 

 

protected void RadContectMenu1_ItemClick(object sender, Telerik.Web.UI.RadMenuEventArgs e)

{

           

int iClickedRowIndex;

      bool convertResult = Int32.TryParse(Request.Params["ClickedRowIndex"], out iClickedRowIndex);

      if (!convertResult) return;

      string clickedCommand = e.Item.Text;

 

       switch (clickedCommand)

       {

                case "Insert":

                    RadGrid1.MasterTableView.IsItemInserted = true;

                    RadGrid_Categories.Rebind();

                    break;

                case "Edit":

                    RadGrid1.Items[iClickedRowIndex].Edit = true;

                    RadGrid_Categories.Rebind();

                    break;

                                 

                    

        }

 

           

}

 

 

protected void RadGrid1_PreRender(object sender, EventArgs e)

{

   GridColumn col = (GridColumn)RadGrid1.MasterTableView.GetColumn("EditCommandColumn");

   if (RadGrid_Categories.EditIndexes.Count > 0 || RadGrid_Categories.MasterTableView.IsItemInserted )

   {

       col.Visible = true;

   }

   else

   {

       col.Visible = false;

   }

  

}

Hi,

Try the following code snippet.

CS:

 protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if ((e.Item is GridEditableItem) && (e.Item.IsInEditMode))
        {
            e.Item.OwnerTableView.IsItemInserted = false;
        }
        else if((e.Item is GridEditFormInsertItem)&&(e.Item.OwnerTableView.IsItemInserted))
       {
        RadGrid1.MasterTableView.ClearEditItems();
       }
     }

Thanks
Shinu.

In the PreRender event, I check

RadGrid_Categories.EditIndexes.Count > 0 || RadGrid_Categories.MasterTableView.IsItemInserted

to hide or display the "EditCommandColumn" column. If in the databind event,  I set IsItemInserted into false, the EditCommandColumn would be always invisible.

Thanks.
