[Solved] Programmatically Create & Bind Data to RadNumericTextBox In RadGrid

[Carl]

I have a very simple table with 3 columns; ID (hidden), Quantity, Amount. The point of the grid is to allow users to add a new row, add values and the keeping adding rows with values. 

I am programatically creating the grid columns specifying the EditItemTemplate of the columns using a class that implements ITemplate as follows:

templateColumn = new GridTemplateColumn();
templateColumn.EditItemTemplate = new RadNumericTextBoxTemplate("txtQuantity", "Quantity");
templateColumn.UniqueName = templateColumn.HeaderText = "Quantity";
templateColumn.DataField = "Quantity";
myGrid.MasterTableView.Columns.Add(templateColumn);

public class RadNumericTextBoxTemplate : TemplateControlDefaults
{
    protected RadNumericTextBox textBox;
    string controlname;
    string bindingName;

    public RadNumericTextBoxTemplate(string ControlName, string BindingName)
    {
        this.controlname = ControlName;

        if (BindingName != string.Empty)
        {
            this.bindingName = BindingName;
        }
    }

    public override void InstantiateIn(System.Web.UI.Control container)
    {
        textBox = new RadNumericTextBox();
        textBox.ID = this.controlname;
        textBox.Skin = defaultTextBoxSkinName;
        textBox.Width = Unit.Pixel(100);

        container.Controls.Add(textBox);
        }
    }

The rows always need to be in Edit mode, InlIne editing in this case:

protected void myGrid_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {
        e.Item.Edit = true;
    }
}

How do I make sure that the items are bound to the text boxes? The data source is an IList<myObject> where myObject has the properties to match the columns (ID, Quantity, Amount).

Any help appreciated.

Hi,

You need to bind the textbox to the Quantity field  using the DataBinding event as shown below.:

public override void InstantiateIn(System.Web.UI.Control container)
    {
        textBox = new RadNumericTextBox();
        textBox.ID = this.controlname;
        textBox.Skin = defaultTextBoxSkinName;
        textBox.Width = Unit.Pixel(100);
        textBox.DataBinding += new EventHandler(textBox_DataBinding);
        container.Controls.Add(textBox);
        }
    }

 public void textBox_DataBinding(object sender, EventArgs e)
  {
     RadNumericTextBox textBox = (RadNumericTextBox)sender;
    GridEditableItem container = (GridEditableItem)textBox.NamingContainer;
     textBox.Text = ((DataRowView)container.DataItem)["Quantity"].ToString()
  }

Thanks,

That pretty much worked.

Thank you.
