GridView Sorting manually

Posted By:      Posted Date: September 16, 2010    Points: 0   Category :ASP.Net
I have searched high and low - and used many solutions to no avail.  I am trying to get my data to sort, but clicking on the headings seems to do nothing at all.  Code is below:GridView control:<asp:GridView ID="GridView1" OnSorting="GridView1_Sorting"                  OnPageIndexChanging="GridView1_PageIndexChanging" runat="server" AllowPaging="True"              AllowSorting="True" AutoGenerateColumns="False" CellPadding="4"              DataKeyNames="CiID" GridLines="None"                  onselectedindexchanged="GridView1_SelectedIndexChanged1" ForeColor="#333333"                  style="font-size: small; font-family: Tahoma"                  PagerSettings-Mode="NextPreviousFirstLast" ShowFooter="True"              Width="100%" > <PagerSettings Mode="NextPreviousFirstLast"></PagerSettings>             <RowStyle BackColor="

Manually coding controls such as gridview, listview, repeater, etc.


using vs2010 and .net 4

In my project I have a separate DAL built from class files that I'd like to use to store my code for CRUD operations against my database.

I'm having a hard time finding examples of how to code server controls like the gridview, listview, repeater etc., for CRUD operations manually, i.e., without a datasource control of some flavor.

I don't have any problem manually coding the referenced controls to get my data, but I do have problems when it comes to coding them to perform CRUD operations unless I use a datasource control. When I use the datasource controls CRUD operations seem to automagically appear out of nowhere after they're configured.

Can someone point me to some samples somewhere? Have I missed a section at MSDN?


Gridview Sorting and Page Orientation


Hi there,

I have looked at several posts on Gridview sorting but can't seem to get it to work in my code. I am using Subsonic objects as the DataSource. Every time I click on a page or sorting link it does a postback but the page orientation is left at the top, not where the gridview is on the page. Is there a way around this?

This is the code I have written for it:

        protected void PublicNoticeGridview_Sorting(Object sender, GridViewSortEventArgs e)
            MidvaleSiteDBDB db = new MidvaleSiteDBDB();
            SqlQuery pubNoticeQuery = db.Select.From<publicnotice>();

Gridview (bound by ObjectDataSource) Sorting - VB.NET

Hello.. I have a gridview being data bound by an objectdatasource which points to a BLL/DAL.  I have paging and sorting enabled within the gridview. I have the fields configured in the look/fell I want from a templatefield.  This templatefield has the sort expression (date) I want things to be sorted by. All this works as it should and I have no issues with it. But, the issue is that when I click on the header to sort asc/desc by date, I have to click on it twice for it switch to descending order.  E.g.  I hit the webpage and it lists all the information in the gridview, sorted by date, ascending order.  If I want to sort by descending order, I have to click the date header twice in order for the gridview to sort the information in descending order; the clicks cause a post-back and the whole screen is refreshed. Any ideas why this may be occurring?  Thanks.. -Jeff

gridview checkbox sorting not working

Hi All,I have a grid view which populates data just for viewing purpose(report) . One field shows the Active/inactive status for which I am showing a checkbox..if data in database is 1 then the checkbox will be checked otherwise it'll not be checked. This field is inactive so that the User does not check/uncheck it. The issue is that this field cannot be sorted. All the fields in the gridview are being sorted. Below is the code for the checkbox column. <asp:TemplateField HeaderText="InActive" SortExpression="Inactive"><HeaderTemplate ><asp:Label ID="lblStat" CssClass="copyLabel" Text="Inactive" CommandArgument="Inactive"                    runat="server"></asp:Label></HeaderTemplate> <ItemTemplate><asp:CheckBox runat="server" ID="chkStatus" Enabled="false"/></ItemTemplate></asp:TemplateField>I have given AllowSorting="True" in the gridview properties. The code in the gridview sorting event works fine for all other columns except the checkbox column. Please help and suggest some scenarios/links so that I can achieve sorting for the checkbox column also.Thanks in advance.
