RadGrid issues

[Ahmed Ilyas]

I am not sure why its complicated or maybe im misunderstanding.

I have a custom datasource.
I programmatically add columns and then on ItemDataBound, I get the currentItem and bind the values from the custom object (currentItem) to the columns in the current row being bound. Great.

But now, I want to retrieve the values (potentially modified values) on an "Update" Command.
So I have an OnItemCommand and it does fire.
However, when trying to retrieve the value, I only get an empty HTML space even though the value is there.

Any ideas where I am going wrong?

protected void radGridMenus_OnItemCommand(object sender, GridCommandEventArgs e)
        {
            GridDataItem currentRow = e.Item as GridDataItem;
            if (currentRow != null)
            {
                switch (e.CommandName.ToLower().Trim())
                {
                    case "update":
                            // currentRow["MenuID"].Value - here it is   Not sure why?
                        break;
                    default:
                        break;
                }
            }
        }

Hello,


please try with below code snippet.

  private void DoSetDefaultMenuColumns()
        {
            // lets create the columns.
            GridBoundColumn menuIDColumn = new GridBoundColumn();
            menuIDColumn.HeaderText = "Menu ID";
            menuIDColumn.DataField = "MenuID";
            menuIDColumn.UniqueName ="MenuID"; // Added new
......
.........

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
        {

            if (e.Item is GridEditableItem && e.Item.IsInEditMode)
            {

                    // update
                    GridEditableItem item = e.Item as GridEditableItem;
                    (item["MenuID"].Controls[0] as TextBox).Text; // access your text here
                }

        }
