Grouping Gridview with jquery

The requirement of the project is to show a table of data with the riskdetails(just for assumption) which have the corresponing values for every month and people used to compare the values for last months.

Building a grouping Grid with GridView and ASP.NET AJAX toolkit CollapsiblePanel

I've posted an update to this post to apply on demand loading of Details data using ASP.NET AJAX PageMethods. I'm demonstrating the usage if CollapsiblePanelExtender client events on the new post. Check it out.

I admit, Matt Berseth is really inspiring me! Few days ago I pass through 2 of his great posts:

.Surrounding your Data Table and Dialog Controls with ComponentArt Styled Panels
.Building a Grouping Grid with the ASP.NET 3.5 LinqDataSource and ListView Controls
The first one is pure design tips one which I used for making good presentation of my demo here. The 2nd post is actually the idea.

CQWP QueryOverride grouping issue



I have extended content query web part and using dynamic caml for query. I specified grouping in toolpart but the same group headers will appear several times. I referred http://sptoolbox.codeplex.com/Thread/View.aspx?ThreadId=33346 and many other posts which said this issue can be solved using OrderBy in the dynamic caml for the same field as grouping.

I tried adding OrderBy in the caml but run into errors. Follwing code works fine if OrderBy is removed:

            public string CreateCAMLQuery(List<string> names)
                StringBuilder sb = new StringBuilder();
                for (int i = 0; i < names.Count; i++)
                    AppendEQ(sb, names[i]);

One Gridview & Multiple CommandText Issue on Paging


Hi All,

I am using a gridview to display data from two separate functions. [VS 2010 on Framework 4]

This works fine without paging. On paging, clicking 'next page' invokes the older data(of function 1) instead of that in the new function (function 2) Cry


' Function 1

cmd.CommandText = "select * from table1,
Dim dTable As DataTable
Dim dataAdapter As SqlDataAdapter
            dTable = New DataTable
            dataAdapter = New SqlDataAdapter(cmd.CommandText, AquisitionString)

'Function 2

cmd.CommandText = "select * from table2,
Dim dTable As DataTable
Dim dataAdapter As SqlDataAdapter
            dTable = New DataTable
            dataAdapter = New SqlDataAdapter(cmd.CommandText, AquisitionString)

            if (Page.IsPostBack)
                this.gvSingleFlightSearch.DataSourceID = "CheckSingleFlightDataSource";

                if (gvSingleFlightSearch.EmptyDataText != null)
                    pnlFlightAvailableMessage.Visible = true;
                    lblAvailableFlights.Text = "Flight Available";
                    gvSingleFlightSearch.Visible = true;


                        pnlFlightAvailableMessage.Visible = false;
                        lblAvailableFlights.Text = "No Flight Available";
                        gvSingleFlightSearch.Visible = false;

(2) one of the field in my grid view is price while a texbox in my booking form is passenger numbers. how can i use the value entered

Issue with row and column Grouping

In my report I have two row groups one below the other that belong to the same parent group. I also have a column group. What happens is until I have only one row group and one column group the report works fine. When I add a second row group below the first one the values are displayed correct for this second row grouping but the values for the first row group which were earlier correct are not shown. The display for those values is blank. Can anyone help with why this is happening? 

GridView and FindControl issue..


Hi guys,

I dont seem to find any control using the FindControl method over gridviews "on edit". I have pasted my code below, please tell me if m doing something wrong or missing something..

ASPX page:

<asp:GridView ID="gvCountry" runat="server" AutoGenerateColumns="False" 
                <asp:TemplateField HeaderText="Edit">
                        <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="True" 
                            CommandName="Update" Text="Update"></asp:LinkButton>
                         <asp:LinkButton ID="LinkButton2" runat="server" CausesValidation="False" 
                            CommandName="Cancel" Text="Cancel"></asp:LinkButton>
                        <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False" 

Grouping gridview with gridhelper returns wrong row index



I'm using a GridView and GridViewHelper Class (http://www.agrinei.com/gridviewhelper/gridviewhelper_en.htm) for grouping the grid by desired field. On the grid I also include an "edit" RowCommand.



ID ... Name ... Company ... Year ... RowCommand



1 ... Alex ... Comp1 ... 1999 ... Edit

2 ... Jane ... Comp2 ... 1999 ... Edit


3 ... Mike ... Comp1 ... 1999 ... Edit

Now when I click edit in the second row of the grid (ID=1, the Group itself is shown in the first row) I have the following code on RowCommand:

// Convert the row index stored in the CommandArgument
                    // property to an Integer.
                    int index = Convert.ToInt32(e.CommandArgument);

                    // Retrieve the row that contains the button clicked 
                    // by the user from the Rows collection.
                    GridViewRow row = GridView1.Rows[index];

and the index returned is 0 instead of 1. Why? And how can I fix this, because the edit command returns error or points to the wrong records??<
