Fill DropDownList in GridView with one duplicate column

Anupam Kakkar

Hi,

I am facing an issue in GridView using a DropDownList. Please help me, I would appreciate it a lot!

legacy_emblem test1
legacy_emblem test2
legacy_emblem test3

The above is the data I need to insert into a GridView.

Here is how I want it.

will have only one value "legacy_emblem"

will have "test1", "test2", "test3"

So, looking at the GridView is should show only 1 Row, like this:

but instead, it shows all the 3 Rows. Also, The DropDownList shows items Vertically and not Horizontally,
like this:

t
e
s
t
1

How do I do it.

Thanks,

Hi,

I used entirely a new method of resolving the problem:

ASPX Page







                                    AutoGenerateColumns="False"
                    onrowdatabound="GridViewOption_RowDataBound"
                    SkinId="CartOption"
                    >

                                                    HeaderStyle-HorizontalAlign="Left"
                            ItemStyle-HorizontalAlign="Left"
                            ItemStyle-Width="1%"
                            ItemStyle-Wrap="false">






                                                    HeaderStyle-HorizontalAlign="Left"
                            ItemStyle-HorizontalAlign="Left"
                            ItemStyle-Width="1%"
                            ItemStyle-Wrap="false">

                                                                    OnSelectedIndexChanged="txtitemid_SelectedIndexChanged"
                                    AutoPostBack="true"
                                    Width="200px">








ASPX.CS PAGE

protected void GridViewOption_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowIndex > -1)
            {
                DropDownList ItemOptionDropDown = e.Row.Cells[1].FindControl("txtitemid") as DropDownList;
                Label ItemOptionLabel = e.Row.Cells[1].FindControl("labeloptions") as Label;
                try
                {

                    CartOpt = this.GetCartOption((int)DataBinder.Eval(e.Row.DataItem, "StoreId"), DataBinder.Eval(e.Row.DataItem, "ItemId").ToString());
                    if (CartOpt.Count > 0)
                    {
                        ItemOptionLabel.Text = DataBinder.Eval(e.Row.DataItem, "ItemId").ToString();
                        foreach (CartOptionInfo ctop in CartOpt)
                        {
                            ItemOptionDropDown.Items.Add(ctop.ElementName);
                        }
                    }
                    else
                        e.Row.Visible = false;
                }
                catch
                {
                    // No Exception Thrown
                }
            }
        }

Thats how I did it. Hope it helps...

Hi,

All the rows are unique, only first column is replicating.

Here is the code you asked for.

For .cs file

if (_option != null) {
GridViewOption.DataSource = _option; GridViewOption.DataBind();
}

For .aspx file

AutoGenerateColumns="False">

HeaderStyle-HorizontalAlign="Left"
ItemStyle-HorizontalAlign="Right"
ItemStyle-Width="1%"
ItemStyle-Wrap="false">

HeaderStyle-HorizontalAlign="Left"
ItemStyle-HorizontalAlign="Right"
ItemStyle-Width="1%"
ItemStyle-Wrap="false">

onselectedindexchanged="txtitemid_SelectedIndexChanged"
AutoPostBack="true" DataSource='<%# Eval("ElementName", "{0:s}") %>' Width="200px">

_option is a List for Type.

Can you paste your code which fills the GridView? I suspect that you have made this Label-DropDownList part of code once for every row which in turn creates three rows in GridView.
