Textbox in headertemplate gridview lost text in updatepanel

Posted By:      Posted Date: September 06, 2010    Points: 0   Category :ASP.Net
Hi everybody,I never post on this forum because since I write code in asp.net I always solve issues by finding solutions with other members who have the problem before me. But this time I don't know how to do...This is my problem : I have a gridview inside an updatepanel and i modified some headers in order to filter the collection. This worked but when my updatepanel is updating, my textbox for the filter clear the value (the text) and lost focus.Is there any solution ?This is my code : <asp:UpdatePanel ID="UpdatePanelOrders" runat="server" UpdateMode="Conditional"> <Triggers> <asp:AsyncPostBackTrigger ControlID="btFilterClear" /> </Triggers> <ContentTemplate> <asp:GridView ID="OrdersView" runat="server" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False" ShowHeaderWhenEmpty="True" EnablePersistedSelection="True" PagerStyle-CssClass="pager" AlternatingRowStyle-CssClass="alter_row" SelectedRowStyle-CssClass="select_row" DataKeyNames="CustId,SalesOrders,CompCode,CustPO"> <Columns>

Textbox Editable GridView in ASP.NET

This article describes how I made a fully editable gridview in C# using ASP.NET 2. The idea is that the GridView looks and works like an Excel spreadsheet. You see all the cells in the table, and you can edit any of the cells you like, and they are automatically updated (i.e. saved to the database). This is very often how people expect data tables to work in web pages, and I've often seen people clicking in vain on un-editable gridview cells, somehow expecting to edit them, and not understanding that they need to click an Edit button at the end of the row.

Editable Gridview with Textbox, CheckBox, Radio Button and DropDown List

This is an example of an editable gridview containing different ASP.NET controls. When user wants to edit values in gridview, she/he can use these controls to edit existing values in Gridview Edit Mode.

jquery datepicker not popping up in Gridview Edit Template textbox


I have a gridview that I can't for the life of me get the datepicker calender to pop up for.  I've been using the datepicker for months very successfully for a variety of textboxes on the page and inside of formviews but this is the first time I've tried using with gridview.  I didn't expect any issues however can't seem to find anything to work.  I have searched the forums for 2 days and attempted any suggestions found within the solutions to no avail.  I've tried using the CSS to link the datepicker but everything stopped working when I changed the code and my page which uses a css style already got all distorted looking.  Please help!

Here is my gridview (only included a part b/c it is large and am only having problem with the datepicker for the date completed text box)

<asp:GridView ID="GridViewCompleted" runat="server" AllowPaging="True" AllowSorting="True"
        AutoGenerateColumns="False" BackColor="#CCCCCC" BorderColor="#999999" BorderStyle="Solid"

Textbox text populated by Session Variable wont update into SQL with new text


Hi everyone, I have what I think is a weird issue. I send text from one page to another via Session Variable. When page 2 loads, the text box has the session text set, but if the user changes the text and clicks the button, the SQL database is update with the original session text. If I remove the redirect from the page 2 button_Click method, then, the page refreshes with the textbox reverting to the session text and thr SQLDataSource has the session text added to it.

Why would the button click cause the textbox refresh with the text from the pageLoad before updating the data source?

gridview tablecell text emptystring in RowDataBound event when editing


HI and thanks in advance.  asp.net using vb, using a codebehind page.

I have a relatively simple gridview bound to an product table that displays great.  The problem comes when I choose to edit a row.  When I do so, the gridviews' RowDataBound event fires and the values of the text properties of the tablecells in the row evaluate to "" emptystring. 

I do notice that if I break within the GridView1_RowDataBound event during a refresh of the page, the values are there.  But again, when I hit the "Edit" button in the first column (the CommandField column) .  Text properties of the cells resolve to ""

 Here is the code for the event, followed by the gridview in the form (inside an updatepanel)

Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
        If e.Row.RowType = DataControlRowType.DataRow Then  ' not a header, footer row.. etc.
            Dim cellProductNumber As TableCell = e.Row.Cells(3) ' ProductNumber column

'>>>>> after clicking "update", even though a value displays in the gridview,
' the cellProductNumber.Te

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?

Value into Textbox of GridView Edit

Hi there, I am not sure this can be done, and if not I am looking for an alternative. Before I start I am using VB.Net and ASP.Net.What I would like to do, is when the edit button is pressed on a Gridview row, I want the TextBox under the ClockOut column, to automatically have the selected value of a dropdown list at the top of the page. Basically so a list of users times will come up in the grid view, and as a fast way to insert a clock out time, the user will have to change the drop down list at the top of the ASP.Net page to the clock out time they want, then when pressing Edit on the row, the time from the Dropdown list will be in the ClockOut textbox, and pressing update will post this. Any help will be great! Thanks, Hope it can be done.

Replace Text in textbox in word document using interop and asp.net

Hi all,  I'm trying to create a function to replace fields in a word document using asp.net. The fields are marked in the document using ###field### and I need to replace them with the data from the DB. The code I have works fine for the body of the word document but doesn't appear to work if the text is contained within a textbox, is there a way to correct this?

TextBox shows binding source text when window load, so why not with the ComboBox?

How can I get a ComboBox to show the binding source value when my window opens?  I have been searching all day for a solution to this, but cannot find anything.  So I have created a sample project to demonstrate my problem.  Below is a Vehicle class, very simple, two members Category and Make.  Category is an enumeration, Make is a string. namespace ComboExample { public class Vehicle { // Constants and enumerations public enum eCategory { Road, Air, Sea } // Attributes public eCategory Category { get; set; } public String Make { get; set; } // Construction public Vehicle(eCategory Category, String strMake) { this.Category = Category; this.Make = strMake; } } } Here is the C# for the MainWindow.  A new Vehicle object is created as a member.  In the constructor I set a data-provider in the XAML to this Vehicle object.  There is a button event for showing the values of the controls and objects so I can check the binding. namespace ComboExample { // Interaction logic for MainWindow.xaml public partial class MainWindow : Window { // Attributes Vehicle m_Car = new Vehicle(Vehicle.eCategory.Road, "BMW"); // Construction public MainWindow() { InitializeComponent(); // link data-p
