CheckBox Controls In Repeater Not Maintaining State?

Nov 10, 2010

Bit confused about this. I was under the impression that if you added server controls to the ItemTemplate of a repeater then the ID's assigned to those controls would persist across postbacks and the state would be maintained. But it doesn't seem to be happening. Here's my ItemTemplate:

[Code]....

Which populates fine. What I'm looking to happen is for the user to be able to select certain items from the repeater using the checkbox and "process" them (i.e. perform some data operations on those items) on clicking a button which is outside the repeater. Here's my button click code:

[Code]....

But if you step through this, the checkboxes are found and assigned correctly but their Checked attribute is always False.

State Management :: Maintaining Viewstate On Gridview With Controls?

Jan 14, 2011

I have a gridview with results from a database query and columns where I add linkbuttons to individual cells.

something like:

Dim LB2 As New LinkButton

LB2.Text = "title"
LB2.CommandArgument = "argument"

AddHandler LB2.Click, AddressOf LaunchDocument

GridView1.Rows(i).Cells(10).Controls.Add(LB2)

There is a lot time involved in determining what cells get the linkbutton and I want to avoid going through that process on a postback when a user clicks one of the linkbuttons.How can I maintain these controls in the gridview after a user clicks a linkbutton and a postback is done?Right now the application has to go through the process all over again.

Maintaining State Across Site In C# .NET

Jul 11, 2010

I have a website that returns search results from Twitter, written in C# ASP.NET. The search works very well.When the user sees the results I want them to also have a 'Next Page' type hyperlink that will perform the search from the last previous result onwards (using Twitter's next_page data). How can I preserve properties so that when a link is clicked it will run the search again with different parameters for the next results? I cannot use Form as there is one Form on the page already and MS limits to one Form per page (for runat="server")

Dropdown In .net Usercontrol Not Maintaining State

Nov 15, 2010

This is probably something fundamental and stupid that I've missed, but the various workarounds are causing me such huge headaches that really, I need to understand the basic problem here in order to find the best solution. I have a usercontrol which contains a drop-down list.

<asp:DropDownList ID="ddlOrderStatus" AutoPostBack="true" runat="server" CssClass="textbox">
<asp:ListItem value="8">Pending</asp:ListItem>
<asp:ListItem value="9">On Hold</asp:ListItem>
<asp:ListItem Value="11">Complete</asp:ListItem>
<asp:ListItem Value="12">Cancelled</asp:ListItem>
</asp:DropDownList>

It does nothing in its Page_Load event. This is in turn contained in a page which, in it's Page_Load event does some databinding on some repeater controls on the page but doesn't touch the control containing the ddl. There is no ajax on the page. The dropdownlist is - clearly - set to autopostback = true. The postback code looks like this:

Private Sub ddlOrderStatus_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ddlOrderStatus.SelectedIndexChanged
Dim ddl As DropDownList = DirectCast(sender, DropDownList)
Dim currentsorting As String = Request.QueryString("sort")
Dim currentpaging As String = Request.QueryString("page")
Response.Redirect(String.Format("~/admin/orders/Manage/0?sort={0}&page={1}&status={2}", currentsorting, currentpaging, ddl.SelectedValue))
End Sub................................

Maintaining Scrollbar Position And Div Tag State On PostBack?

Feb 26, 2010

I have a web page that regularly refreshes on post back, and all of this works fine. However, a user has made enhance the page, which I need with:

1) There are 3 asp.panels on the page, which are scrollable vertically. When the page refreshes, the scroll position returns to the top. The enhancement is to maintain the position of where ever the scrollbar is on postback. How do I keep the scrollbar position on post back?

2) Within each of the panels are dynamically added web controls. These web controls contain gridviews, which are themselves contained inside div tags. These div tags can be hiddened and made visible by an image button. This hidden and visible state is actioned by some javascript on the page. Again, the user has asked how it is possible to maintain the state of these div tags on post back, i.e. those that are closed and those that are visible. Currently, the state is on postback for all the div tags to be visible. How do I maintain the state of the visibility of a div tag during postback?

Forms Data Controls :: Binding To Checkbox In Repeater?

Jan 19, 2010

I have a couple of Checkbox controls in the Item Template of a Repeater and am trying to set them (checked or not) based on an underlying data value. With Labels the <%# Bind... > syntax can be used but there does not seem to be an equivelent for a Checkbox.

So I have moved into the code, specifically the ItemDataBound handler of the Repeater control but cannot seem to instantiate the Checkbox controls.

In the handler repProjectList_ItemDataBound(object sender, RepeaterItemEventArgs e) I can instantiate the Repeater by casting sender or the RepeaterItem by using e.item and both have FindControl() methods but neither seem to find my Checkbox.

Further, once I am able to 'find' the Checkbox, I'm not sure how to reference the various values in the underlying data source.

Forms Data Controls :: Binding To Checkbox Checked When Using A Repeater

Dec 20, 2010

i have a database of values that I am rendering in a table via the repeater control. (Previously I was using a gridview but I know require a repeater) I have a checkbox being 'repeated' for each record and I can get the id of each row to do some logic, but what I cannot get is whether it is checked or not as the value is null. As the database has no null values, I can only asume it is not binding for the checkboxes as current true values do not have a check in the box. The onCheckedChanged event carries out the logic required to change whether record is disabled via the database. With a gridview

Checked='<%# Bind ("Disabled")%>' was enough
<td
class="GridCentre"[code]....

is this done with the itemdatabound event? and how is it done?

Feb 23, 2011

I had a webform, in which I included the ajax control toolkit. From that, I inserted the tab control on to my webform, having 4 tabs in that tabcontainer. So, I am allowing the end user to enter the information in the first 3 tab panels, and want to display the entered info on the 4 tab panel, which shows all the info entered in the 3 tab panels.

So, how should I manage the information, and display the entered information on the 4th tab panel.. I had some plans of implementing an accordian ajax control for each 3 tabs info, allowing the user to edit at the 4th tab itself..Is this the right idea, or else suggest me, how to display the all the entered info in the 4th tab,like can i use details view, or grid,or suggest something else!!! I added a button to each panel, so that after the user enters the information, he will be redireted to the next tab panel after firing the "Save and continue" button.

AFter the user confirms the data on the 4th tab panel, and presses the submit button, then the entered info has to be entered into the database, for this to happen,. whtat should i do...??Can you plz help me out with some detailed explanation, as I am newbie , need support from you kind of ppl...In the first tab, I had some 4 text boxes, and 3 dropdowns, and a save and continue buttton, and in the next panel, some more text

Forms Data Controls :: Maintain Checkbox State On Multiple GridViews With DropDownList?

Jan 20, 2011

I have a multiView control within which I have 3 views as part of building a customer order.

Step 1: Customer is selected from gridView and Customer Name is saved in MultiView Session.

Step 2: Products are chosen from gridView. The grid is re-bound depending on which product category is selected in a dropDownList. The product details are also stored.

Step 3: All of the details required to build the INSERT query are passed to labels on a form to be reviewed before committing to db. The next stage, now that I have managed to select multiple rows, will be to display this data in another gridView.

Everything works fine, except for the paging and dropDownList which is causing the checkbox state to be lost after postBack.

I've read a few articles on this, but I think I have made the task more complicated due to the dropDownList in addition to paging. Essentially the customer will be able to select various product lines, across various bindings of the gridView so I need to persist the checkbox state and retain the data for the INSERT query.
