  Not Able to Assign Rating value to gridview label using asp.net C# using Visual Studio 2013

  Apr 26, 2017 11:27 AM|mazhar khan india|LINK

  I have a gridview and Inside gridview have AjaxControlToolkit rating control and label. I Want to assign rating value to gridview label but value is coming inside Rating1_Changed event but after assign to label then not showing in gridview. If I will keep rating control autopostback=true means Rating1_Changed is not firing.

       <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="FruitName"
                  DataSourceID="SqlDataSource1">
                  <Columns>
                      <asp:TemplateField HeaderText="Rating Star">
                          <ItemTemplate>
                              <asp:Rating ID="Rating1" runat="server" CurrentRating="1" MaxRating="5" RatingAlign="Horizontal"
                                  RatingDirection="LeftToRightTopToBottom" StarCssClass="ratingStar" WaitingStarCssClass="savedRatingStar"
                                  FilledStarCssClass="filledRatingStar" EmptyStarCssClass="emptyRatingStar" OnChanged="Rating1_Changed">
                              </asp:Rating>
                          </ItemTemplate>
                      </asp:TemplateField>
                      <asp:BoundField DataField="FruitName" HeaderText="FruitName" ReadOnly="True" SortExpression="FruitName" />
  
                      <asp:TemplateField HeaderText="rating">
                          <ItemTemplate>
                              <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
                          </ItemTemplate>
                      </asp:TemplateField>
  
                  </Columns>
              </asp:GridView>
              <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:xlr8ap_ConnectionString %>"
                  SelectCommand="SELECT * FROM [Fruits]"></asp:SqlDataSource>

  Below is my code behind c#.

    protected void Rating1_Changed(object sender,  AjaxControlToolkit.RatingEventArgs e)
  {
      AjaxControlToolkit.Rating myRating =
                (AjaxControlToolkit.Rating)sender;
      System.Text.RegularExpressions.Regex rexLineNo =
        new System.Text.RegularExpressions.Regex("ctl\\d+");
  
      string a = e.Value;
  
     Label someLabel = (sender as Control).Parent.FindControl("Label1") as Label;
     someLabel.Text = a;
  
  }

  Why If I will keep rating control to autopostback=true means not firing. Please help to out this.

  Dear mgebhard,

  your answer is below like that here I explain easy way.

  First, you need to explain what "it does not work" means.  Could the issue be the page logic redirects before the OnChange event fires?

  Hi mazhar,

  Not Able to Assign Rating value to gridview label using asp.net C# using Visual Studio 2013

  As for this issue, I suggest you could refer to the following code:

  <%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>
  
  
      <style type="text/css">
          .Star {
              background-image: url(../Images/Star.gif);
              height: 17px;
              width: 17px;
          }
  
          .WaitingStar {
              background-image: url(../Images/WaitingStar.gif);
              height: 17px;
              width: 17px;
          }
  
          .FilledStar {
              background-image: url(../Images/FilledStar.gif);
              height: 17px;
              width: 17px;
          }
      </style>
  
          <div>
              <asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server"></asp:ToolkitScriptManager>
           
              <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="ID" DataSourceID="SqlDataSource1">
                  <Columns>
                      <asp:BoundField DataField="ID" HeaderText="ID" ReadOnly="True" SortExpression="ID" />
                      <asp:BoundField DataField="Name" HeaderText="Name" SortExpression="Name" />
                      <asp:TemplateField HeaderText="Rating">
                          <ItemTemplate>
                              <asp:Rating ID="Rating1" AutoPostBack="true" OnChanged="Rating1_Changed" runat="server"
                                  StarCssClass="Star" WaitingStarCssClass="WaitingStar" EmptyStarCssClass="Star"
                                  FilledStarCssClass="FilledStar">
                              </asp:Rating>
                          </ItemTemplate>
                      </asp:TemplateField>
                      <asp:TemplateField HeaderText="Value">
                          <ItemTemplate>
                              <asp:Label ID="lblRating" runat="server" Text=""></asp:Label>
                          </ItemTemplate>
                      </asp:TemplateField>
                  </Columns>
              </asp:GridView>
              <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:MyTestDBConnStr2 %>" SelectCommand="SELECT [ID], [Name] FROM [Table3]"></asp:SqlDataSource>
          </div>

  Code behind:

          protected void Rating1_Changed(object sender, AjaxControlToolkit.RatingEventArgs e)
          {
              AjaxControlToolkit.Rating rating = (AjaxControlToolkit.Rating)sender; //get the rating control
              string value = e.Value; //get rating value.
              GridViewRow row = (GridViewRow)rating.NamingContainer; //using NamingContainer to find the GridViewRow
              Label lbl = (Label)row.FindControl("lblRating"); //using the findcontrol method to find the label
              lbl.Text = value; //set the value.
          }
