Update panel problem in gridview footer


On my aspx page, I'm having troubles when I have an update panel within the footer template of a gridview. It appears to be an intermitent problem that occurs on subsequent postback when you do a delete command in the gridview. The first delete command always goes through fine (first postback). Clicking on another row to delete on the gridview (or any other button on the form) triggers this error:

An error has occurred because a control with id 'ctl00$SupremeContent$grdLineNumbers$ctl09$ctl00' could not be located or a different control is assigned to the same ID after postback. If the ID is not assigned, explicitly set the ID property of controls that raise postback events to avoid this error.

If you click the back button in the browser, then click on another page, then come back to this page, you can delete another record. Another attempt to delete another record brings you back to the above problem. Thectl00$SupremeContent$grdLineNumbers$ctl09$ctl00 changes each time you delete, come back to the page and delete.

If I disable the udpate panel, there's no errors.

The reason I have the update panel is so that the user can select the relevant pipe specification (they see multiple columns using a textbox, drop down extender, panel and gridview) without the form's data being reset by the embedded gridview's

Problem in Gridview - Only first row updated, Rest not updated.


Dear All,


I have detailsview [dtlviewRecommendation], bounded with Linq DataSource [LinqDataSourceRecommendation]. In the Item Template and Edit Template in the DetailsView, I have a GridView[gvItemRecommendation] bounded with LinqDatasource[LinqDataSourceRecommendation].

When I'm editing[For Updation] the data in the gridview [Edit mode of the DetailsView], all the data are not updated in the DB except the first row.

Only Precisely, first GridViewrow is updated. Rest of Gridview row are not updated in the database.

void LinqDataSourceRecommendation_Updating  -> Hitted once.

Any can one suggest the solution for this.



Gridview update problem with related tables


Hi all,

I have a problem in getting my gridview to update. The datasource gets its data from 2 related tables using the following select statement:

SELECT StudentSubject.StudentID, Students.[1stName], Students.Surname, Students.Grade, StudentSubject.Subject, StudentSubject.GradeOverall, StudentSubject.ReportYear, StudentSubject.ReportSession, StudentSubject.Criteria1Grade, StudentSubject.Criteria2Grade, StudentSubject.Criteria3Grade, StudentSubject.Criteria4Grade, StudentSubject.Criteria5Grade, StudentSubject.Criteria6Grade, StudentSubject.Criteria7Grade, StudentSubject.Criteria8Grade, StudentSubject.Criteria9Grade, StudentSubject.Criteria10Grade, StudentSubject.Comment
FROM (Students INNER JOIN StudentSubject ON Students.StudentID = StudentSubject.StudentID)
WHERE (StudentSubject.Subject = ?) AND (StudentSubject.ReportYear = ?) AND (Students.Grade = ?) AND (StudentSubject.ReportSession = ?)

The ? stem from combo box controls which I use to filter the results

So far so good!

However, when I try to update the data in just one of the tables, nothing happens, no error, just no update. The update statement I'm using is:

UPDATE StudentSubject SET GradeOverall = ?, Criteria1Grade = ?, Criteria8Grade = ?, Criteria7Grade = ?, Criteria6Grade = ?, Criteria5Grade = ?, Criteria4Grade = ?, Criteria3Grade = ?, Criteria2Grade = ?, Criteria

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.

Problem to group radio button across gridview rows

In general no one can easily group or make a single selection from radio button list inside gridview rows. There are a lot of way to make a single or unique selection from list. Here i want to share how i can address this problem in the most easiest way. Googling the problem most of the cases i saw the grouping in horizontal way. Thats why i tried to group the radio buttons in vertical manner. Let i have a requirement like below:

Gridview Enable Selection Problem



I have a gridview with Enable selection and Enable Paging equals to TRUE.

I also set the PageSize of my gridview to 4 so that I only displays 4 rows per page.

The problem is when I click the pager in the bottom of my gridview, my gridview is disappearing and no records appear.

Here is code behind of my gridview:

If e.Row.RowType = DataControlRowType.DataRow Then
                e.Row.Attributes("style") = "cursor:pointer"

                e.Row.Cells(2).Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(sender, "Select$" & e.Row.RowIndex.ToString))
                e.Row.Cells(3).Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(sender, "Select$" & e.Row.RowIndex.ToString))
                e.Row.Cells(4).Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(sender, "Select$" & e.Row.RowIndex.ToString))
                e.Row.Cells(5).Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(sender, "Select$" & e.Row.RowIndex.ToString))
                e.Row.Cells(6).Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(sender, "Select$" & e.Row.RowIndex.ToString))

Excel-like experience - gridview focus problem



I'm creating a page where people can order several items from a list without having to press "edit" and "save" in between like you normally would in a gridview. The user writes down the quantity, and finally presses a "submit" button that saves the order.

I want the user to have a windows form (or excel) like eperience, so once the user puts in the quantity and moves on to the next item, either by TAB or by clicking on the TextBox, i make some calculations without the user beeing bothered with a full refresh or having to press a buton to execute the event, so I place the controls inside an UpdatePanel and use TextBox.TextChanged. The event runs code that calculates the sum for the row (price * quantity) and shows that in a column called "Sum", and updates a label in a fixed position with the new order total ("Total").

Any ideas on how to achieve this?

Right now I use a GridView with a templatefield for the Quantity and set the TextBox.TextChanged event to fire to make the calculations. The problem is that the focus then changes.

By using SmartNavigation or the ScriptManager.SetFocus I manage to retain focus on the TextBox that executed the Postback, but the user might have moved on to a textbox far down the gridview (thus causing the postback by leaving the previo

GridView Problem


I've been asked to change an ASP.NET project to MVP Architecture - which may have something to do with what is going wrong.

I make the call through the architecture to the database which returns a dataset which I've verified is correct, (using dataset.writeXML() ) just before databinding  to the gridview.

On one page everything works as expected (plus any post backs). Another page the Page_Load works correct and the gridview is populated, but any postbacks do not work- it retains the Page_Load's data. Then on the third page the GridView never shows though databinded. In all these cases I've checked that the Dataset is good data, and made sure to DataBind().

All three use the exact same logic. Any ideas or suggestions are greatly appreicated.

Thank you for your help.

public partial class UI_Admin_manageFirms : System.Web.UI.Page, IManageFirms_Pres
    static ManageFirms_Pres presentation;

    protected void Page_Load(object sender, EventArgs e)
        if (!Page.IsPostBack)
            presentation = new ManageFirms_Pres(this);

    protected void btnSearch_Click(object sender, EventArgs e)
        string firmName = (txtFirmName.Text != string.Empty) ? txtFirmName.Text : null;

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
