Unable to select checkbox of RadListBox in RadGrid

[sunil]

I am creating a RadGrid programmatically. It has 2 template columns as well.
When we click Edit button for a row then, one template column has to be changed to a dropdown and other column should be changed to RadListbox of checkboxes.

Also, the ItemTemplate value should be used to select the appropriate checkboxes ni the RadListBox.

I have written the code to select the ListBoxItems of RadListBox, but it doesn't work. Can some help.

The code I have written is of this way:-


In RadGrid's Item Data Bound event:-

GridDataItem gridDataItem = e.Item as GridDataItem;

            DataRowView dvRow = gridDataItem.DataItem as DataRowView;

if (e.Item is GridEditableItem && e.Item.IsInEditMode)
     {
         GridDataItem gridDataItem = e.Item as GridDataItem;
         DataRowView dvRow = gridDataItem.DataItem as DataRowView;

         RadComboBox cmbPositionID = gridDataItem.FindControl("comboPositionID") as RadComboBox;

         cmbPositionID.SelectedValue = dvRow["PositionID"].ToString();

         RadListBox listBox = gridDataItem.FindControl("comboLanguageID") as RadListBox;

         string value = dvRow["LanguageID"].ToString();

         string[] values = value.Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries);
         foreach (string val in values)
         {
             RadListBoxItem item = listBox.FindItemByText(val);
             if (item != null)
                 item.Selected = true;
         }


     }

lic partial class Default : System.Web.UI.Page

{

    DataTable _userDT = new DataTable();

    DataTable _positionDT = new DataTable();

    DataTable _languageDT = new DataTable();

    RadGrid RadGrid1 = null;

    protected void Page_Load(object sender, EventArgs e)

    {

        if (!IsPostBack)

        {

            RadGrid1.DataBind(); 

    }

public partial class Default : System.Web.UI.Page

{

    DataTable _userDT = new DataTable();

    DataTable _positionDT = new DataTable();

    DataTable _languageDT = new DataTable();

    RadGrid RadGrid1 = null;

    protected void Page_Load(object sender, EventArgs e)

    {

        if (!IsPostBack)

        {

            RadGrid1.DataBind();

        }

    }

public partial class Default : System.Web.UI.Page

{

    DataTable _userDT = new DataTable();

    DataTable _positionDT = new DataTable();

    DataTable _languageDT = new DataTable();

  sdfasdfsadf  RadGrid RadGrid1 = null;

Hello Sunil,

You can select RadListBox item by setting Checked property of RadListBoxItem as true.

C#:

foreach (string val in values)
  {
      RadListBoxItem item = listBox.FindItemByText(val);
      if (item != null)
         item.Checked = true;
  }

Thanks,
Princy.

I tried using Checked property as well..but of no use.

Hi sunil,

Can you confirm that the code in the ItemDataBound event handler is executed as expected?

Other than this, if the Checked property of an item is set to true, this should check the default CheckBox of the RadListBox item. If you are using ItemTemplate for the RadListBox items with custom CheckBox controls, then you need to find the particular checkbox and set its Checked property.

Yes the code executes properly and I am not using any custom check box control. You can look at my code in my initial post

Hello sunil,

I used the already suggested approach in the attached sample and it works as expected in my side. Try it on your end and let me know how it goes and if I missed something from your logic out.

Kind regards,
