View 24 RepliesI 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.

Platform: ASP.Net 2.0 I have multiple checkboxlist controls on a webpage. Along with that i have the same number of buttons on that page. Initially all the checkboxlist controls are hidden. When user clicks on a button, corresponding checkboxlist controls gets visible making others hidden and allows user to select the options.
On postback, if user clicks on the same button again, the corresponding checkboxlist gets visible but the item selection is not retained. However, this happens only in IE. This works fine in FireFox. I am using JQuery to toggle the visibility of checkboxlist.I guess the problem is because i am toggling the visibility of checkboxlist which IE doesnt seem to like. What is the solution to this problem?
I'm using the asp.net PreviousPage functionality and cross-page postback. The problem i'm running into is that if I have any postbacks on my page, the PreviousPage information seems to be lost. I don't want to put it in ViewState because that will be quite large. I've thought about Session, but I don't want the data to persist after i've moved on to another page, and I really don't like the idea of putting code in all my other pages to delete old session variables.
View 1 RepliesI have a ASP DropDownList that gets populated on the Page_Load event, after i select an item and hit a button the selected item gets cleared and the first item in the DropDownList gets selected. (The DropDownList is only populated when the page is not postback)

List<Country> lCountries = new List<Country>();

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??
I have created a composite control with sample details as follows. Basically, the first time on page load the control sets a view state variable and the problem is that on post back (when the button is clicked), the ViewState variable is null. I have researched extensively and I am not able to find a solution. I checked all the Microsoft recommended articles and also from other developers. This approach seem to work for everyone
PS: This code may not work as it is only for illustrative purposes. but this is exactly what i'm doing in my code.

handle site navigation and retaining user selections.
On Page 1:
I am using an <asp:ListBox as a filter for an <asp:GridView (gv.datasource=myobj.getdata(lb.selectedvalue))
This functions as expected and the gridview pagination functions as expected.
Each row on the grid provides an <asp:HyperLinkField to navigate to another page (Page 2).
This functions as expected.
On Page 2:
This provides functionality to perform some data creation/manipulation tasks.
It also provides a link to navigate to another page where other tasks can be performed (Page 3).
My query is in relation to returning from Page 3 to Page 2 to Page 1.
I would like to be able to return from Page 3 to Page2 to Page 1 and display earlier selections.
Currently, I am using a combination of querystring parameters and sessions vars on each Page_Load to achieve this.
Q1: What are the recommended ways to achieve this?
Q2: Is it possible to dynamically specify url parameters on a sitemap?

I want to open a aspx page in new window.
I am openning a web page using JavaScript open .
StringBuilder cstext3 = new StringBuilder();
cstext3.Append("<script type=text/javascript> function OpenPreviewPage() {");
cstext3.Append("open('Preview.aspx');");
cstext3.Append("} </script>");
And executing following at button click on .cs page
protected void btnPreview_Click(object sender, ImageClickEventArgs e)
{
/*This will call the OpenPreviewPage method of java script from .cs file */
string javaScript =
"<script language=JavaScript>
" +
"OpenPreviewPage();
" +
"</script>";
RegisterStartupScript("ShowPreviewPage", javaScript);
}
The problem is the PreviousPage tag in preview page is null.
repPFareDetail = PreviousPage.FindControl("repFareDetail") as Repeater;
Is there any other way to open the aspx in new window by retaining the PreviousPage.FindControl method.
I have a comboBox within a grid. Basically to get it I have to use findcontrol. I am thinking of another option however. Within the init method I was planning on getting the value and storing it to a private static field:
private static RadComboBox theComboBox
Is it unwise to be storing a relatively complex object like this in a static field?

View 1 RepliesI'm trying to retain "visible" property of a control using view state in the following way
public bool showstatusbox {

Is there anything I should do other than this to retain value. Because, though I store the value in view state, on postback, its becoming null.

I have a simple ASP.NET page where after the initial page load the user enters a username and a password to two text boxes. Note that I can not use the built-in login control in ASP.NET, as my purpose of using this username and password is slightly different.Now, I want the user to enter the said two values only once. Afterwards, using those two values I perform several tasks. Now here's the tricky part; since I set the TextMode property of the password text box to 'password', every time a button click occurs it clears the password field, and since every button click event triggers a page load as well, I lose the password data. But I do not want the user to keep entering the password every time he has to click a button.How can I retain the username and password in my code? If this were a normal .NET Windows Application, I would use a global variable and assign the value the first time and I would have it available to me throughout the life cycle of my program. But how can I do it here?
View 1 RepliesI have a very simple user control with 5 radio buttons on it, and 3 properties (ID, RatingSetID, and Rating). On the initial load of the page they are on, the code acquires data and places the data into the 3 properties. However, when the submit button is clicked the page reloads and the 3 properties get reset to 0, they are in the !IsPostBack as well.
