Web Forms :: RadioButton - Dynamically Created Not Retaining Checked Value After Postback

Jan 13, 2011

I have a couple of RadioButtons that are created dynamically. But after postback they don't retain their checked property. I also have some CheckBoxes and they work just fine using the same mechanism (code below). I have narrowed down the problem to the "GroupName" property. If I remove it, it works just fine. But I need the RadioButtons to be mutually exclusive.

.net - Checkbox Within Datagrid Retaining Checked Value On Postback In VB.NET But Not C#?

Feb 24, 2011

I have a project in VB.NET which is working fine which essentially has a Datagrid that has a TemplateColumn included which is a column of Checkboxes. The code to declare the datagrid is here...

<asp:datagrid id="dgDates" OnItemCommand="gridEventHandler" BorderColor="Black" BorderWidth="1px"
CellPadding="3" runat="server" AutoGenerateColumns="False" HorizontalAlign="Left" AllowSorting="True"
OnSortCommand="SortData" OnItemDataBound="gridItemDataBound">
<HeaderStyle Font-Underline="True" Font-Bold="True" HorizontalAlign="Center" ForeColor="Black"
BackColor="#D4D0C8"></HeaderStyle>
<Columns>
<asp:BoundColumn DataField="strParameterName" SortExpression="strParameterName" HeaderText="Parameter Name"></asp:BoundColumn>
<asp:BoundColumn DataField="dtParameterValue" SortExpression="dtParameterValue" HeaderText="Parameter Value"></asp:BoundColumn>
<asp:TemplateColumn HeaderText="Constant" SortExpression="blnStatic" ItemStyle-HorizontalAlign="Center">
<ItemTemplate>
<asp:CheckBox ID="cbStaticRolling" Checked="False" Runat="server" AutoPostBack="true"></asp:CheckBox>
</ItemTemplate>
</asp:TemplateColumn>
</Columns>

as you can see the Checkbox has Autopostback="true" but there are other things on the page which produce postbacks as well.

My Page_load has this in it, being called on every load of the page, postbacks included...

Dim strGUID As String
strGUID = Session("strGUID")
dgDates.DataSource = SqlHelper.ExecuteDataset(ConfigurationManager.AppSettings(Web. [Global].CfgKeyConnStringADMIN), "dbo.spRptGetSchedulingDates", strGUID)
dgDates.DataBind()
intNumberOfDates = dgDates.Items().Count

as well my code behind has the following code for the gridItemDataBound

Protected Sub gridItemDataBound(ByVal sender As System.Object, ByVal e As System.Web.UI.WebControls.DataGridItemEventArgs)
'hide the intRptSchedulingDatesID for each row in the checkbox's content style variable
If (e.Item.ItemType = ListItemType.Item Or e.Item.ItemType = ListItemType.AlternatingItem) Then
CType(e.Item.FindControl("cbStaticRolling"), CheckBox).Style("Content") = CType(e.Item.DataItem, System.Data.DataRowView).Item("intRptSchedulingDatesID")
End If
End Sub

everything you see sbove is working perfectly fine...in the sense that when I click one of the checkboxes, the page_load fires, the gridItemDataBound fires on DataBind() and when all is done, the checkbox retains the value that the user clicked the checkbox.

With all this exact same code converted to C#....the events all fire in the same order, but the checkbox selected value always clears...any thoughts??

Web Forms :: Set RadioButton To Checked Dynamically

Sep 8, 2010

I'd like to set one of a few radiobuttons to checked dynamically. They are called rbTheme1-rbTheme7. I can find them (for example the one called rbTheme3) with the code below but how do I set it to true at the loading of the page?

int buttonID = 3;
string buttonName = "rbTheme";
(RadioButton)themePick.FindControl("buttonName" + buttonID.ToString());

Web Forms :: Custom RadioButton Loses Checked Value On PostBack?

Jan 28, 2010

I am creating a control that inherits from the RadioButton, so that I can set the GroupName property manually. Everything is working okay apart from the fact that when the page posts back, the RadioButton becomes unchecked if it has previously been checked. This is the first time I've tried inheriting from controls, so must be doing something really silly. I would welcome anyone helping me to improve my code so that the control's Checked value persists through postbacks. I am causing a postback using a button, not the actual RadioButton itself, if that makes any difference. Here is my code:

C# - Retaining Viewstate In Textboxes Found In A Dynamically Created Table?

Feb 3, 2010

My problem is that I have an ASPX page which contains an ASP:Table. The rows for the table is added dynamically on Page_Load. One column in the table contains TextBoxes, BUT when I type something on a TextBox and cause a postback, I am unable to find the value just entered. And above that the table is not displayed after the postback.Can anyone help me please? I want to keep the table viewstate with the modified textbox values, so that when i post back to server, I can intercept these new values.

Web Forms :: Dynamically Created Table Will Not Appear After Postback?

Jun 7, 2010

In my code I create a table dynamically and I try to restore the table after a postback. But although I recreate the table during the Page_Load event with the same id's before,the table doesn't appear with the same state and values as before.

I think it will be a typically beginner error, but I wasn't be able to locate the error whereas reading different posts and tutorials related to this topic.

//Code behind
protected void Page_Load(object sender, EventArgs e)
{
if (Page.IsPostBack & _hfsubmittedURL.Value == "tbCreated")
{
TableRow row1 = new TableRow();

Web Forms :: Saving Dynamically Created Tabs On PostBack?

Nov 8, 2010

I know this has been asked before, but I feel like I'm losing my way trying to follow the other examples out there. Does anyone see a straightforward solution to my particular problem?

Goal:

Two column Master Page

Left column contains a list of [stuff] (I'm trying a Repeater with LinkButtons)

Right column contains a TabContainer which will add dynamically created tabs when buttons on the left are clicked.

Left side looks like this:

<asp:Repeater
<ItemTemplate>
<asp:LinkButton ID="lbShowReport" runat="server" Text='<%# Eval("Title") %>' CommandName="Select">
</asp:LinkButton>
<asp:HiddenField ID="hfReportID" runat="server" Value='<%# Eval("Id") %>' />
</ItemTemplate>
</asp:Repeater>

I had initially been creating tabs in the LB's OnCommand event, but of course this means that any tab generated by one click is lost if the user clicks another LinkButton.

So I moved the code to create a new tab to the OnInit section of the page and attempted to loop through the RepeaterItems comparing the UniqueId of each LinkButton until I found the one that was clicked using Request.Form["__EVENTTARGET"].

When I tried to loop through the RepeaterItems, however, the count was always 0, and the Repeater would not populate.

So now I am rebinding the Repeater in the Init section on every post-back - this allows me to find the LinkButton that was clicked. I then add the new Tab based on the LB that was clicked like this:

[Code]....

This properly adds new Tabs to the TabContainer using this code:

[Code]....

but I still have the issue where I can only ever have one dynamically created tab in the TabContainer at a time. All of the code above is being executed in OnInit, which I thought would save the tabs during post-backs, but instead this is behaving as tho I was adding the tabs in the OnCommand event of the Link Button...

Forms Data Controls :: Dynamically Created Checkbox In GridView Are Lost In The Postback?

Mar 3, 2010

In design time I created a Gridview and a delete button in a page test.aspx:

[Code]....

The program stopped at statement "if ((row.Cells[COL_INDEX_SELECTED].Controls[0] as CheckBox).Checked)",

because it cannot find the checkbox created before.

I tried to shift all the code in Page_Load to Page_Init, but the ticked checkboxes are still lost.

I could find the ticked checkboxes names in its request object parameters(this.Request.Params.AllKey) if I setup a breakpoint on the error statement.

Does anyone konw what's happening and how to retrieve the selected rows?

Forms Data Controls :: Dynamically Created TextBox In GridView Does Not Show Updated Value After Postback?

May 10, 2010

I have a grid view that is dynamically created.In which every cell in the girdview has a 2 textbox (cTxtboxQty,ctxtWorkOrder) and 2 label.

When user click on the cell, a pop up come out and user are able to change the text inside the cell and click save.After that the pop up close and changed data immediately reflected on the screen.

My problem is:

After my data are changed and updated to database on the pop up page and having it post back to the parent page , my dynamically created textbox in gridview retain old value even new value has been assigned to it.

This sound very weird but i have no idea how to solve this.

My client side code is as below :

[Code]....

[Code]....

I have tested many times and find out that it might be the page hold the old value in memory, so that even we have updated the textbox value, after postback, it still keep and show the old value?

Dynamically Created Controls And Postback

Nov 18, 2010

I know this question has been asked thousands of times, and I've struggled with it before, but for some reason, I can't accomplish what I want to accomplish... I have a dynamically added LinkButton that when clicked will dynamically add a control (in this example, a textbox) to the same panel. The intent is to continuously add on as many controls as times the LinkButton was clicked (i.e. I click it once, one box, then another click will give me 2 boxes, another click adds a 3rd). In the code below, I use the current date and time serialized to create a unique ID for each textbox control.

When I execute the code, clicking "Add Filter" will generate a new textbox, but once clicked again will create a new one, and dispose of the one before it. Instead, I want to persist the previous textbox as well as any data submitted within it.In the aspx:

<asp:Panel ID="pnlFilter" runat="server">

</asp:Panel>

In the aspx.cs:

protected void Page_Init(object sender, EventArgs e)
{
LinkButton lb = new LinkButton(); [code]....

AJAX :: How To Hook Dynamically Created Controls To Do A Partial Postback

Oct 7, 2010

So I have two UpdatePanels. I am dynamically creating server-side buttons in UpdatePanel2. When the buttons come out, they are not hooked to the asynchronoustriggers of updatePanel1.

So how can I dynamically add these triggers of these newly dynamically created buttons so that clicking these buttons will only cause a partial postback to UpdatePanel1 ? Right now, when I click these buttons, it causes a partial-postback refresh to UpdatePanel2 (the panel itself that which the controls reside in)
