  how to get value from gridview

  Apr 10, 2008 07:34 AM|LINK

  Hi,

   I'm a beginner with ajax, i use visual studio 2005 and ajax is installed on my computer!

  I have a gridview with a column select and on this column i'd like to put a link to a function javascript (alert)

  for displaying some information about the row ?

  Sample click on row 1 result : > alert('Your name is ' + UserName+ 'Your surname is : ' + Surnmae)

  someone can help me to do that ? 

  Thanks for all

  Christophe

   Hi,

       In gridview selected index changing event you get the current row index and values based on that,. and have a clientscript message for alert.

  Hi

  Use the below code to get the value from the Gridview on selection of Row 

  dim a as string
  
  
  dim b as string
  
  
  a=GridView1.DataKeys(GridView1.SelectedIndex).Values("UserName").ToString()
  
  
  b=GridView1.DataKeys(GridView1.SelectedIndex).Values("Surnmae").ToString()

   

   The Value you are accessing from the gridview like for EX:UserName,Surname these you have write in the Gridview Tag --> DataKeyNames="UserName,Surname"

     

     <asp:GridView ID="GridView1" DataKeyNames="UserName,Surname"  runat="server" BackColor="#CCCCCC" BorderColor="#999999"
                  BorderStyle="Solid" BorderWidth="3px" CellPadding="4" CellSpacing="2"
                  ForeColor="Black" Height="210px"
                  Style="z-index: 100; left: 2px; position: absolute; top: -5px" Width="279px" OnSelectedIndexChanged="GridView1_SelectedIndexChanged"  >
                  <FooterStyle BackColor="#CCCCCC" /><Columns>
                      <asp:CommandField ShowSelectButton="True" />
                  </Columns>
                   <SelectedRowStyle BackColor="#000099" Font-Bold="True" ForeColor="White" />
    </asp:GridView>

  And if you have a problem with this please let me know 

   
  
  Thanks

  Here's a working example

   
  <script type="text/javascript" language="javascript">
  
  function alertuser()
  {
  
    var user = document.getElementById('<%= HiddenField1.ClientID %>').value;
  
    if (confirm("Your Name is "+ "" + User)==true)
      return true;
    else
      return false;
  }
  
  </script>
  
  <asp:HiddenField ID="HiddenField1" runat="server" />
  <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" OnSelectedIndexChanged="GridView1_SelectedIndexChanged" OnRowUpdating="GridView1_RowUpdating">
      <Columns>
          <asp:CommandField ShowSelectButton="True" />
          <asp:BoundField />
          <asp:BoundField />
          <asp:TemplateField>
              <ItemTemplate>
                  <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
              </ItemTemplate>
          </asp:TemplateField>
      </Columns>
  </asp:GridView>
  
  RELEVANT CODES
  
      private void bindDummy()
      {
  
          DataTable dt = new DataTable();
  
          dt.Columns.Add("Val1");
          dt.Columns.Add("Val2");
          dt.Columns.Add("val3");
          DataRow dr = dt.NewRow();
          dr["Val1"] = "value1";
          dr["Val2"] = "value2";
          dr["Val3"] = "value3";
          dt.Rows.Add(dr);
  
  
          GridView1.DataSource = dt;
          GridView1.DataBind();
  
      }
      protected void Page_Load(object sender, EventArgs e)
      {
          HiddenField1.Value = User.Identity.Name.ToString();
          if (!Page.IsPostBack)
          {
              bindDummy();
          }
      }
      protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
      {
          for (int i = 0; i < GridView1.Rows.Count; i++)
          {
              if (GridView1.SelectedIndex == i)
              {
                  LinkButton lb = (LinkButton) GridView1.Rows[i].Cells[0].Controls[0];
          
                  if (lb != null)
                  {
                      lb.Attributes.Add("onclick", "javascript:return alertuser();");
                  }
              }
          }
      }

  I have tested on this and works fine..
