Answer 2

On the ASP page, you need to set the GroupName property to the same for all radio buttons, for example:

 <asp:RadioButton ID="RadioButton1" runat="server" GroupName="RadioGroup" /> 

Answer 3

well for this you can use follwing code first you must define groupName.The follwing code will work

  <asp:RadioButton ID="RadioButton1" OnCheckedChanged="rbSelector_CheckedChanged" AutoPostBack="true" GroupName="Apply" runat="server"></asp:RadioButton> 

WITH#

 protected void rbSelector_CheckedChanged(object sender, System.EventArgs e) { foreach (GridViewRow oldrow in GridView2.Rows) { ((RadioButton)oldrow.FindControl("RadioButton1")).Checked = false; } //Set the new selected row RadioButton rb = (RadioButton)sender; GridViewRow row = (GridViewRow)rb.NamingContainer; ((RadioButton)row.FindControl("RadioButton1")).Checked = true; }

You can try this link to select a single radio block in the grid: http://www.c-sharpcorner.com/uploadfile/krishnasarala/select-single-radio-button-in-gridview-in-Asp-Net/

Answer 5

Using the GroupName property alone will not work, each switch will still receive a unique attribute for the name, since it is located on different grid lines.

One option is to manually break the switch markup using the Literal control ( example ). This will make it possible to easily group radio buttons on the client side, but it requires a bit more work to determine which button was selected during postback.

When I needed this behavior, it was easier for me to keep the radio buttons as server-side controls and just apply the w / jQuery button group. Put the RadioButton in the TemplateField, as you showed, then add this code to uncheck all the other buttons if one of them is checked:

 $(document).ready(function () { // could also pass in a unique ID selector createManualRadioButtonGroupForGridView(".myGridViewClass"); }); function createManualRadioButtonGroupForGridView(gridViewSelector) { $(gridViewSelector + " input[type=radio]").change(function () { var checkedRadioButton = this; $(gridViewSelector + " input[type=radio]").each(function (e) { if (this !== checkedRadioButton) { $(this).prop("checked", false); } }); }); }
