Associating asp-button in gridview with code-behind function

Question

I am new to Vb.net. I am using gridview and binding it a resultset from database. I am trying to use asp button and associate a codebehind function with it.

But since the rows are generating dynamically, ids of button are incrementing accordingly.

Here is the code -

'<asp:GridView ID="grdProjects" runat="server" CssClass="q_acontent" Width="990px"
AutoGenerateColumns="false" CellPadding="2" ClientIDMode="static" ViewStateMode="Enabled">
<asp:TemplateField HeaderText="Document Name">
<ItemTemplate>
<asp:Button ID="Button3" runat="server" Text='<%# (Convert.ToString(DataBinder.Eval(Container.DataItem, "Data_text")))%>'/>
</ItemTemplate>
<ItemStyle Width="5%" HorizontalAlign="Center" CssClass="conatact_phone  breakword" />
</asp:TemplateField>
</asp:GridView>'

Please help me how to associate codebehind function and pass its corresponding button text to it.

Use the OnCommand event of button controls and Set the CommandArgument property of the button to your DataItem value as:

<ItemTemplate>
<asp:Button ID="Button3" runat="server" 
 Text='<%# (Convert.ToString(DataBinder.Eval(Container.DataItem,"Data_text")))%>'
 OnCommand="Button3_Command" 
 CommandArgument='<%# (Convert.ToString(DataBinder.Eval(Container.DataItem,
                  "Data_text")))%>'
        />
</ItemTemplate>

OnCommand event in your code behind file:

Public Sub Button3_Command(sender As Object, e As CommandEventArgs)
    Dim _dataText As String = e.CommandArgument.ToString()

End Sub
