ASP.Net Gridview Edit Update Cancel Commands

In ASP.Net 2.0, GridView Control also provides the functionality to edit and update the data retrieved from the database using CommandField template. You can cancel the action using Cancel Command of the CommandField. GridView consists of events that can be used to perform the actions like edit, update and cancel upon the Data items displayed in the ASP.Net GridView Data Control.

How to format and update GridView and DataGrid rows using JQuery

The behavior described in this question is as expected. When you set text of a cell in grid, it directly affects HTML that is going to be rendered. When you set text value of a cell, it means that you are setting innerText of the cell. The column that GridView creates for command fields (Edit, Delete and Select) are a (anchor) or button elements. So you can see what will happen if you set text value in that cell. It will wipe out those link or button controls and replace them with simple text string.

Visual Studio closes itself by opening aspx-Page designer after Windows Update


Hey Guys,

I've a problem with my Visual Studio.

On the 13th of August 2010 i installed a Windows update on my vista sp2 pc. For this date my Visual Studio 2008 sp 1 always has closed itself by opening an aspx-page in designer view. There is no error message just closing the window. I restored a backup of my windows from the time before updating it and it helped, i could open aspx pages in the design view till the update has been installed again automatically after rebooting the pc. I can't disable windows updates, cause it's my pc at work and safety is very important. I hope you could help me out of this disaster.

Gridview extends past edge of div and page when editing users


I have a gridview pulling all data from one user. This gridview has an edit button and when that is clicked the gridview becomes too wide for the div/screen and I get a scroll bar. Since this gridview can only have one user in it anyway is it possible to display each field on seperate lines instead?

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 Update outside of SqlDatasource


Is it possible to use a SQLDataSource to populate a gridview but not use the SQLDataSource for Updating?

I wanted to add the update code in the Gridview_RowUpdating event since it is a complex update I need to do.

I get this message when i click the update button

Updating is not supported by data source 'SqlDataSource1' unless UpdateCommand is specified.

Problem with master page and update panel (I think)



the app I am working with is made up of three nested master pages that have the following design:

The first master page ha only realize the HEADER, BODY and FOOTER divs.

The second one specialize the Body content placeholder and divide it in three more layers: NAVIGATOR, PAGE TITLE, BODY CONTENT.

The final layer specialize the BODY CONTENT in PAGE CONTENT and ACTIONS.

In one of my content pages I have (inside the PAGE CONTENT area) 

  • 1 Update Panel that contains a gridview object
  • 1 Update Panel that contains some HTML code to show in a PopupModalExtender

The PopupModalExtender can be either triggered from inside the gridView and also from a series of LinkButtons that are in the ACTIONS area.

The problem is that when the PopupModalExtender shows the FOOTER and the ACTIONS areas are not dimmed from the style I apply as background to the modal popup. An example of what I am trying to explain can be viewed in the following screenshot.

Why this is going to happen? Has anybody any suggestion on how to solve this problem?

Thanks a lot

Changing a textbox's readonly property right before update on a gridview


I have a gridview with a date field. I don't want the user to be able to type in their own date and mess up the format so I made the property readonly. That date is then set by a point and click interface. This is all working fine but when the user clicks update this field doesn't update because it's readonly. If i turn readonly off it works so is there a way to turn off the readonly property right before submit?

How to return back to a specific page in a gridview list?

Hello,  I have a gridview with paging. So for instance, I'm on say the page number 10, and I open the form details on a specific record_id (link). After I update/submit the form, it returns to page number 10. But, if I go to another page, for instance page 5, and submit the form, it returns to page 10. I've tried some things, for instance history.back(), but it returns to the first page I went to, in this case page number 10 (or whatever the first page I go to). Hopefully this code helps to understand what I'm asking: <asp:GridView DataKeyNames="Referral ID" ID="gvList" runat="server" CellPadding="4"     ForeColor="#333333" GridLines="None" OnRowCommand="gvList_RowCommand"     OnRowDataBound="gvList_RowDataBound" OnRowDeleted="gvList_RowDeleted"     OnRowDeleting="gvList_RowDeleting" AllowPaging="True" PageSize="20"     AutoGenerateColumns="False" OnPageIndexChanging="gvList_PageIndexChanging"    OnRowCreated="OnRowCreated" AllowSorting="True" OnSorting="OnSort"> protected void gvList_PageIndexChanging(object sender, GridViewPageEventArgs e)        {   &nb
