  Conditional message alert box

  Nov 30, 2012 04:16 PM|LINK

  I have some code that executes when a button is clicked in a gridview control like this:

  if(test == "0")

  {

        // Do some stuff

  }

  else

  {

      // Here I want to display a popup alert box if test != 0

  }

  So how can I display an alert box test != "0"?  Remember, the button is in a gridview control.

  In the message area do this:

  alert("Thanks for visiting!");

  Put this - Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "script", "alert('Message')", true);

  on button click ....you must be capturing button click inside gridview's rowcommand event.

  Message area?  Not sure what you mean.

  Test this sample code:

  HTML

  <asp:GridView ID="gv" runat="server" AutoGenerateColumns="false" OnRowCommand="gv_RowCommand">
          <Columns>
              <asp:TemplateField HeaderText="Button Field">
                  <ItemTemplate>
                      <asp:Button ID="btn" runat="server" Text="Go" CommandName="click" />
                  </ItemTemplate>
              </asp:TemplateField>
          </Columns>
  </asp:GridView>

  C#

  protected void Page_Load(object sender, EventArgs ex)
  {
          if (!IsPostBack)
          {
              DataTable dt = GetData();
  
              gv.DataSource = dt;
              gv.DataBind();
          }
  }
  protected DataTable GetData()
  {
          DataTable table = new DataTable();
          table.Columns.Add("ID", Type.GetType("System.Double"));
          table.Columns.Add("InterviewDate");
  
          DataRow row = table.NewRow();
          row["ID"] = "11.22";
          row["InterviewDate"] = "01/01/2001";
          table.Rows.Add(row);
  
          row = table.NewRow();
          row["ID"] = "7144.00";
          row["InterviewDate"] = "01/01/2001";
          table.Rows.Add(row);
  
          row = table.NewRow();
          row["ID"] = "2122.4";
          row["InterviewDate"] = "01/01/2001";
          table.Rows.Add(row);
  
          return table;
  }
  protected void gv_RowCommand(object sender, GridViewCommandEventArgs e)
  {
          if (e.CommandName == "click")
          {
             //Put condition here
              Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "script", "alert('Message')", true);
          }
  }

  I hope you get the idea.
