Hello All,
             In my radgrid I have two edit columns, I am following the example shown here http://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/form-template-update/defaultcs.aspx
each edit column is  created programmatically as follows:

Edit Column one
C#
GridEditCommandColumn EditColumn = new GridEditCommandColumn();
            RadGrid1.MasterTableView.Columns.Add(EditColumn);
            EditColumn.ButtonType = GridButtonColumnType.ImageButton;
            EditColumn.UniqueName = "EditCommandColumn";
            EditColumn.HeaderText = "SingleAction";
            EditColumn.ColumnGroupName = "SingleAction";
            EditColumn.HeaderStyle.CssClass = "RadHeader";
The second Edit Column:
C#
GridButtonColumn DetailColumn = new GridButtonColumn();
            RadGrid1.MasterTableView.Columns.Add(DetailColumn);
            DetailColumn.CommandName = "Edit";
            DetailColumn.Text = "Detail";
            DetailColumn.ButtonType = GridButtonColumnType.ImageButton;
            DetailColumn.UniqueName = "EditCommandColumn1";
            DetailColumn.HeaderText = "SingleAction";
            DetailColumn.ColumnGroupName = "SingleAction";
            DetailColumn.HeaderStyle.CssClass = "RadHeader";
And  OnEditCommand="RadGrid1_EditCommand"
C#
protected void RadGrid1_EditCommand(object sender, GridCommandEventArgs e)
        {
                   if (e.Item is GridDataItem)
                {
                    if (((ImageButton)e.CommandSource).AlternateText == "Detail")
                    {
                        dynamic DItem = e.Item.DataItem;
                        Session.Add("PropValue", DItem.SisUserId);
                        Session.Add("ExistingUser", ExistingUsers);
                        Session.Add("UserEnrollment", UserEnrollment);
                        RadGrid1.MasterTableView.EditFormSettings.UserControlName = "DesktopModules/MyModule/Detail.ascx";
                        RadGrid1.MasterTableView.EditFormSettings.EditFormType = GridEditFormType.WebUserControl;
                        RadGrid1.MasterTableView.EditFormSettings.EditColumn.UniqueName = "EditCommandColumn2";
                          }
                    GridEditFormItem FormItem = (e.Item as GridDataItem).EditFormItem as GridEditFormItem;
                }
           // }
             
        }
In the Detail.aspx I have some text boxes and an Update Button and things look good until I click on the update button. 
OnClick of the update button inside Detail.aspx the button click is not fired, but the interesting thing is that the grid reloads and shows the values a default edit button in Radgrid displays. It shows the column values of the radgrid and not the values in the details.aspx. 

For some reason I cannot fathom why would the grid reload and show the default edit page in the radgrid
Any help is really appreciated. 

Thank you

Hi,

I guess you want to add a WebUserControl editform for your detail table. Please try the following code snippet.

C#:
GridTableView tableViewOrders = new GridTableView(grid);
tableViewOrders.DataSourceID = "SqlDataSource2";
tableViewOrders.DataKeyNames = new string[] { "OrderID" };
tableViewOrders.Name = "Details";
// Adding the WebUserControl form
tableViewOrders.EditFormSettings.EditFormType = GridEditFormType.WebUserControl;
tableViewOrders.EditFormSettings.UserControlName = "DetailsCS.ascx";
tableViewOrders.EditFormSettings.EditColumn.UniqueName = "EditCommandDetail";
 
GridRelationFields relationFields = new GridRelationFields();
relationFields.MasterKeyField = "DataFieldName";
relationFields.DetailKeyField = "DataFieldName";
tableViewOrders.ParentTableRelation.Add(relationFields);
grid.MasterTableView.DetailTables.Add(tableViewOrders);
 
GridButtonColumn DetailColumn = new GridButtonColumn();          
DetailColumn.CommandName = "Edit";
DetailColumn.Text = "Detail";
DetailColumn.ButtonType = GridButtonColumnType.ImageButton;
DetailColumn.UniqueName = "EditCommand";
DetailColumn.HeaderText = "SingleAction";
DetailColumn.ColumnGroupName = "SingleAction";
tableViewOrders.Columns.Add(DetailColumn);

Thanks,
Princy

Hi Princy,
               Thank you for the reply, but let me try to explain the situation a little better. I am able to show the controls in the form and display some values in them depending on the row selected. But, when I click on the Update button (control that I added) the radgrid reloads and displays only the default controls  a edit button would show and not the controls that I added in my Detail.ascx. Now does this explanation change anything in your answer?

Cheers

Hi,

I tried your code and it works fine at my end. I guess you have two buttons for edit, one button you want to open UserControlEditForm and on the other normal editform. Please try the following code snippet. If this doesn't help, provide your full code snippet and the exact steps to reproduce the issue.

C#:
void grid_EditCommand(object sender, GridCommandEventArgs e)
{
    if (((ImageButton)e.CommandSource).AlternateText == "Detail")
    {
        grid.MasterTableView.EditFormSettings.UserControlName ="DesktopModules/MyModule/Detail.ascx";
        grid.MasterTableView.EditFormSettings.EditFormType = GridEditFormType.WebUserControl;
        grid.MasterTableView.EditFormSettings.EditColumn.UniqueName = "EditCommandColumn2";     
    }
    else
    {
        grid.MasterTableView.EditFormSettings.EditFormType = GridEditFormType.AutoGenerated;
    }
}

Thanks,
Princy

Hi Princy,
               Yes you are correct. And I am successful in creating a UserControlForm that open when I click on one edit button and the autogenerated  form when I click on the other button. Inside the UserControlFrom I have an Update Button when clicked I want to perform some operation. The issue is that when I click on this Update button in the UserControl Form it open the autogenerated form and doesnot trigger the onclick event of the Update button. I hope I am clear.  The code below is what I want to trigger on clicking the update button in the UserControlForm, but the radgrid open the autogenerated edit form and this does not make sense to me. 

Thank you
protected void DetailUpdate_Click(object sender, EventArgs e)
       {
           var host = new Host();
           host.Url = "http://test.com";
           host.AccessToken = "1234";
 
 
           string SisUserId = Session["PropValue"].ToString();
           List<User> ExistingUser = (List<User>)Session["ExistingUser"];
           List<Enrollment> UserEnrollment = (List<Enrollment>)Session["UserEnrollment"];
 
           var CoursesEnrolled = UserEnrollment.FindAll(u => u.User.SisUserId == SisUserId);
           var UpdateCourse = new UpdateCoursesAccessPoint();
           foreach(var course in CoursesEnrolled)
           {
               TextBox txt = PlaceHolder1.FindControl("CourseText") as TextBox;
               string value = txt.Text;
           }
 
       }

Hi,

Can you move the code to ItemCommand and see if it works, also change the DetailColumn.CommandName = "EditDetail" . Please try the following code snippet.

C#:
void grid_ItemCommand(object sender, GridCommandEventArgs e)
{
    if (e.CommandName == "EditDetail")
    {
        e.Item.Edit = true;
        grid.MasterTableView.EditFormSettings.UserControlName ="~/DesktopModules/MyModule/Detail.ascx";
        grid.MasterTableView.EditFormSettings.EditFormType = GridEditFormType.WebUserControl;
        grid.MasterTableView.EditFormSettings.EditColumn.UniqueName = "EditCommandColumn2";
        grid.Rebind();
    }
    else
    {
        grid.MasterTableView.EditFormSettings.EditFormType = GridEditFormType.AutoGenerated;
    }
}

Thanks,
Princy

Hi Princy,
               Thank you for your time,but, unfortunately the problem persists. When I click on the Update button inside the Detail.ascx, the default edit form open up.

    }
Please look at it and see where I am going wrong. For some reason when I click on the Update1 button in the Details.ascx it open up the default edit form.

Hi ,

Make sure that you create the radgrid completely from code behind in Page_Init() event. Then the DetailUpdate button in the UserControl page didn't have the OnClick function attached. Please make these changes and see if it helps.Other than this,i couldn't find any issue.

ASPX:
<asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder>

C#:
RadGrid RadGrid1;
   protected void Page_Init(object source, System.EventArgs e)
   {
       RadGrid1 = new RadGrid();       
       RadGrid1.AutoGenerateColumns = false;
       RadGrid1.NeedDataSource+=new GridNeedDataSourceEventHandler(RadGrid1_NeedDataSource);     
       RadGrid1.ItemCommand +=new GridCommandEventHandler(RadGrid1_ItemCommand);
       . . . . .
       this.PlaceHolder1.Controls.Add(RadGrid1);
    }

ASCX:
<asp:Button ID="DetailUpdate" runat="server" Text="Update1" CommandName="Update"
 OnClick="DetailUpdate_Click1" />

Thanks,
Princy

Hi Princy,
               Before I go ahead and make those changes, I wanted to just make sure. How would creating the RadGrid in PageInit give the UserControl form detail button OnClick  functionality. Please explain, I really appreciate your time.

Thank you

Hey Princy
              I went ahead and did what you suggested. But, this wont work too. I click on the update button in the UserControlForm and it open the default edit form. Now it is getting annoying because of the fact that, I can't figure out what is triggering the default web form to open.

Please try to see if there is something that I am missing.

Thank you

Hi ,

In your code I see that you have created the Radgrid in ASPX page and its columns are created in code behind. Its better to create the entire RadGrid from CodeBehind in the Page_Init event. Next I see that you have set properties like ShowFilterIcon="false" AllowMultiRowSelection="true" etc in the MasterTableView tag, which are not part of the MasterTableView properties. Third in you ASCX page, you haven't added the OnClick event of the "DetailUpdate" button. The code works fine at my end when these changes are made. Below is a sample code snippet that i tried, please try to compare it with your code. Put breakpoints and see if all the events are fired properly.

ASPX:
<asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder>

ASPX:CS:
RadGrid grid;
protected void Page_Init(object sender, EventArgs e)
{
    grid= new RadGrid();
    grid.AutoGenerateColumns = false;    
    grid.MasterTableView.DataKeyNames = new string[] { "CustomerID" };
    grid.AllowPaging = true;
    grid.Skin = "Outlook";
    grid.NeedDataSource += new GridNeedDataSourceEventHandler(grid_NeedDataSource);
    grid.ItemCommand += new GridCommandEventHandler(grid_ItemCommand);    
 
    GridBoundColumn boundColumn1 = new GridBoundColumn();
    grid.MasterTableView.Columns.Add(boundColumn1);
    boundColumn1.DataField = "ContactName";

Hi Princy,
               Thank you for your time and patience through this saga. This is what I did and it things are working now. 

ASPX:
<telerik:RadGrid runat="server" ID="RadGrid1"  AllowSorting="true"  skin="WebBlue"
    AllowMultiRowSelection="true" EnableLinqExpressions="False" PageSize="50"
    OnPageIndexChanged="RadGrid1_PageIndexChanged"  OnPreRender="RadGrid1_PreRender"
    OnNeedDataSource="RadGrid1_NeedDataSource" ShowStatusBar="true" EnableViewState="true"
     OnItemCommand="RadGrid1_ItemCommand">
     
    <mastertableview>
             
        <columns>
          </columns>
//this is what I added  
         <EditFormSettings UserControlName="DesktopModules/MyModule/Detail.ascx" EditFormType="WebUserControl">
                <EditColumn UniqueName="EditCommandColumn1">
                </EditColumn>
            </EditFormSettings>
 
     </mastertableview>
   </telerik:RadGrid>
The code behind remains the same.
And this is the Detail.ascx. I have to say that I deleted the OnClick while pasting the code in the post. But, I agree, it would not have worked without the Onclick
<asp:Table ID="Table2" runat="server">
   <asp:TableHeaderRow id="Table1HeaderRow"
            BackColor="LightBlue"
            runat="server">
            <asp:TableHeaderCell
                Scope="Column"
                Text="Course Name" />
            <asp:TableHeaderCell 
                Scope="Column"
                Text="Section Name" />
            <asp:TableHeaderCell
                Scope="Column"
                Text="Enrollment Type" />
       <asp:TableHeaderCell
                Scope="Column"
                Text="View Access" />
        </asp:TableHeaderRow>           
    <asp:TableRow>
        <asp:TableCell><asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder></asp:TableCell>
        <asp:TableCell><asp:PlaceHolder ID="PlaceHodler2" runat="server"></asp:PlaceHolder></asp:TableCell>
        <asp:TableCell><asp:PlaceHolder ID="PlaceHolder3" runat="server"></asp:PlaceHolder></asp:TableCell>
        <asp:TableCell VerticalAlign="Middle" HorizontalAlign="Center"><asp:PlaceHolder ID="PlaceHolder4" runat="server"></asp:PlaceHolder></asp:TableCell>
     </asp:TableRow>
    <asp:TableRow></asp:TableRow>
    <asp:TableRow>
        <asp:TableCell>
            <asp:Button ID="DetailUpdate" runat="server" Text="Update" CommandName="Update" OnClick="DetailUpdate_Click"/>
        </asp:TableCell>
    </asp:TableRow>
</asp:Table>
The code behind for Detail.ascx also remains the same.

Thank you for you time.
