Change column name on edit mode

[Sravanthi]

I have a radgrid with advanced databinding. it has a template column with combobox on edit mode as follows.

 <telerik:GridTemplateColumn HeaderText="MemberType" EditFormColumnIndex="0" UniqueName="MemberType" SortExpression="MemberType">
                <ItemTemplate>                
                    <asp:Label ID="lblMemberType" runat="server" Text='<%# Eval("MemberType") %>'></asp:Label>                    
                </ItemTemplate>
                <EditItemTemplate>
                <telerik:RadComboBox runat="server" ID="cmbMemberTypes" DataTextField="Description" DataValueField="MemberTypeId" 
                    AppendDataBoundItems="true" MarkFirstMatch="true" OnSelectedIndexChanged="cmbMemberTypes_SelectedIndexChanged" >
                    <Items>
                        <telerik:RadComboBoxItem Text="" Value="" />
                    </Items>
                </telerik:RadComboBox>
                </EditItemTemplate>
            </telerik:GridTemplateColumn>

 
Now, depending on the item selected in the Member Type combobox, i want to change the text of the column 'MemberIdentifier' on Edit mode. I dont need to change Header Text. I just need to change the auto-generated label of this column in edit mode based on Member Type Selected Item.

        <telerik:GridBoundColumn DataField="MemberIdentifier" HeaderText="MemberIdentifier" UniqueName="MemberIdentifier"
                SortExpression="MemberIdentifier" FilterControlAltText="Filter Member Identifier Column" EditFormColumnIndex="1"/>

Thanks for the help in advance!!

Hello,

protected void cmbMemberTypes_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)
        {
            ((sender as RadComboBox).Parent.Parent.Controls[0] as TableCell).Text = ((sender as RadComboBox).Parent.Parent.Controls[0] as TableCell).Text.Replace("MemberType:", "yourtext");
        }

Thanks,

Thanks Jayesh! But, it is changing the name of the Column on the Grid. I want the name of the label that it produces in Edit mode like here in the Image.

Hi,

Try the following code to achieve your scenario.
C#:

protected void RadComboBox1_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)
{
        RadGrid1.Rebind();
}

Thanks,
Shinu

Hello,

Please try with below code snippet.

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="False" OnNeedDataSource="RadGrid1_NeedDataSource"
            AllowPaging="true" AllowFilteringByColumn="true" ShowFooter="true" AllowMultiRowSelection="true"
            AllowMultiRowEdit="true" PageSize="10"

                <Columns>

            <PagerStyle AlwaysVisible="True" />

        </telerik:RadGrid>

   protected void cmbMemberTypes_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)
   {
        TableCell cell = (sender as RadComboBox).Parent.Parent.Controls[0] as TableCell;
        cell.Text = cell.Text.Substring(0, cell.Text.IndexOf(">") + 1) + "Your Text:" +DateTime.Now.ToString() + "</label>";
   }

protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
   {
       dynamic data = new[] {
           new { ID = 1, Name ="Name1",path="1.jpg",Customedate=DateTime.Now,ReceivedDate=DateTime.Now.AddDays(1)},

            new { ID = 4, Name = "Name4",path="2.jpg",Customedate=DateTime.Now,ReceivedDate=DateTime.Now.AddDays(4)},

           new { ID = 10, Name = "Name5",path="3.jpg",Customedate=DateTime.Now,ReceivedDate=DateTime.Now.AddDays(10)},
            new { ID = 11, Name ="Name1",path="1.jpg",Customedate=DateTime.Now,ReceivedDate=DateTime.Now.AddDays(11)},
           new { ID = 12, Name = "Name2",path="2.jpg",Customedate=DateTime.Now,ReceivedDate=DateTime.Now.AddDays(12)},
           new { ID = 13, Name = "Name3",path="3.jpg",Customedate=DateTime.Now,ReceivedDate=DateTime.Now.AddDays(13)},
            new { ID = 14, Name = "Name4",path="2.jpg",Customedate=DateTime.Now,ReceivedDate=DateTime.Now.AddDays(14)},
           new { ID = 15, Name = "Name5",path="3.jpg",Customedate=DateTime.Now,ReceivedDate=DateTime.Now.AddDays(150)}

       };

       RadGrid1.DataSource = data;

   }

Note : You can see that in screenshot no 3 and 4 only in edit label Membertype changed with Yourtext.

Sorry for the Confusion Jayesh. It is changing the text of drop down member type. But, i am trying to change the label of another column 'member identifier' based on 'member type'  selection.

Thanks so much for the help!!

[Sravanthi]

Shinu, your answer is modifying the label. But, when it does the rebind, it is losing the combobox selected item. 

Thanks for the reply!!

Hello,

protected void cmbMemberTypes_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)
        {
            TableCell cell = (sender as RadComboBox).Parent.Parent.Controls[0] as TableCell;
            cell.Text = cell.Text.Substring(0, cell.Text.IndexOf(">") + 1) + "Your Text:" + DateTime.Now.ToString() + "</label>";

            // By using below code i am able to access "Name" column Title
            TableCell cellNAme = ((((sender as RadComboBox).NamingContainer as GridEditableItem)["Name"].Controls[0] as TextBox).Parent.Parent.Controls[0] as TableCell);
            cellNAme.Text = cellNAme.Text.Substring(0, cellNAme.Text.IndexOf(">") + 1) + "Your Text:" + DateTime.Now.ToString() + "</label>";
        }

Thanks Jayesh!! That worked!!

[Qing]

As for me I would like to change the text of    HeaderText="MemberType" dynamically for Insert Mode and Edit Mode. How can I do ? Please kindly help me. Thanks a lot.

[Attila Antal]

Hi Qing,

Check out the Distinguish Edit or Insert Mode article for an example to understand which edit mode is used then use this approach to implement the required behavior.

Kind regards,
Attila Antal
