How to get row data by clicking a button in a row in an ASP.NET gridview

Question

I have a GridView in a ASP.NET web application, in which I have added two buttons in each row:

 <ItemTemplate>     <asp:Button ID="btnEdit" Text="Edit" runat="server" />     <asp:Button ID="btnDelete" Text="Delete" runat="server"/>  </ItemTemplate> 

Now how I can get the row data from gridview simply by clicking an edit button in a row?

Answer 1

You can also use button click event like this:

<asp:TemplateField>     <ItemTemplate>         <asp:Button ID="Button1" runat="server" Text="Button"                      OnClick="MyButtonClick" />     </ItemTemplate> </asp:TemplateField> 

protected void MyButtonClick(object sender, System.EventArgs e) {     //Get the button that raised the event     Button btn = (Button)sender;      //Get the row that contains this button     GridViewRow gvr = (GridViewRow)btn.NamingContainer; }  

OR

You can do like this to get data:

 void CustomersGridView_RowCommand(Object sender, GridViewCommandEventArgs e)  {      // If multiple ButtonField column fields are used, use the     // CommandName property to determine which button was clicked.     if(e.CommandName=="Select")     {       // Convert the row index stored in the CommandArgument       // property to an Integer.       int index = Convert.ToInt32(e.CommandArgument);            // Get the last name of the selected author from the appropriate       // cell in the GridView control.       GridViewRow selectedRow = CustomersGridView.Rows[index];     } } 

and Button in gridview should have command like this and handle rowcommand event:

<asp:gridview id="CustomersGridView"          datasourceid="CustomersSqlDataSource"          autogeneratecolumns="false"         onrowcommand="CustomersGridView_RowCommand"         runat="server">          <columns>           <asp:buttonfield buttontype="Button"              commandname="Select"             headertext="Select Customer"              text="Select"/>         </columns>   </asp:gridview>

Answer 2

Place the commandName in .aspx page

 <asp:Button  ID="btnDelete" Text="Delete" runat="server" CssClass="CoolButtons" CommandName="DeleteData"/> 

Subscribe the rowCommand event for the grid and you can try like this,

protected void grdBillingdata_RowCommand(object sender, GridViewCommandEventArgs e) {         if (e.CommandName == "DeleteData")         {             GridViewRow row = (GridViewRow)(((Button)e.CommandSource).NamingContainer);             HiddenField hdnDataId = (HiddenField)row.FindControl("hdnDataId");          } }
