Get value of GridDropDownColumn in codebehind?

[al]

how can i get the value of GridDropDownColumn in codebehind?

GridEditFormInsertItem dataInsertItem = e.Item as GridEditFormInsertItem;

DropDownList ddlType = dataInsertItem["Type"].Controls[0] as DropDownList;

i used this code in the former radgrid 2.0, but it does not work in th e Q1 grid (formerly prometheus)

What about if the grid is not in edit mode and you're just curious what the value from that database is for that column for that row???????

Hi Mike,

In this case, you can access the cell, which would correspond to this column in the row, and get the value. It will correspond to the value coming from the database.

Hi Mike,

You can try the following code snippet if  want to access the value of the GridDropDownColumn in normal mode.

ASPX:

 <telerik:GridDropDownColumn UniqueName="DropCol"   HeaderText="DropCol"  DataField="ProductName" DataSourceID="SqlDataSource1" ListTextField="ProductName" ListValueField="ProductName"  ></telerik:GridDropDownColumn>

CS:

  protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridDataItem)
        {
            GridDataItem item = (GridDataItem)e.Item;
            string strTxt = item["DropCol"].Text.ToString();
        }
    }

Thanks
Shinu.

This returns the GridDropDownColumn's Text not Value for me. I need the bound value. I think it might be easier to have a hidden GridBoundColumn with the ID I need in addition to the DropDown.

Hello Peter,

Could you please elaborate more on in what event you want to extract the value? Note that the drop down becomes available when the item is being opened for edit. That said you can extract its value by subscribing to the OnItemDataBound event of the grid and obtaining a reference to the drop down.

C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
   {
       GridEditableItem editItem = e.Item as GridEditableItem;
       if (editItem != null && editItem.IsInEditMode)
       {
           string value = (editItem["ColumnName"].Controls[0] as DropDownList).SelectedValue;
       }
   }

Additionally you can try obtaining the bound value in read mode by accessing the DataItem.

C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        GridDataItem item = e.Item as GridDataItem;
        if (item != null)
        {
            string value = ((System.Data.DataRowView)(item.DataItem)).Row["ColumnName"].ToString();
        }
    }
