Forms Data Controls :: Change Literal In A Repeater After A Postback?

Jul 9, 2010

I want to change the value of a literal within a repeater ItemTemplate after postback, based on a value detected at postback.I can't render the whole repeater again though I think because it's actually a radio button in the control that inititates the postback and so I need that control / value to be persisted.

Forms Data Controls :: Firing Postback From Repeater Row Click?

Jul 19, 2010

I have a repeater which contains a hidden link button that fires when I click a row in my repeater.

Here is the markup for my repeater:

<div id="divResults" style="height: 290px; overflow-y: auto;">
<asp:Label ID="lblNote" runat="server" Text="Note: select a row to edit."></asp:Label> [code]...

Here is the javascript thats added to each row in the rptLocations_ItemDataBound:

Row.Attributes.Add("onclick",
"javascript:__doPostBack('ctl00$mainContent$rptLocations$ctl0" + (e.Item.ItemIndex + 1).ToString() +
"$lbtn_SelectRow','')");

When I click the repeater row it fires the SetLocationControls method. As you can see my repeater is wrapped in a DIV of height 290px. When the are more than 9 rows in my repeater you have to scroll the div down to view this row. When I click this row it does the postback but doesn't fire the SetLocationControls method. I've had a look in the source it's created the click event to the repeater row like all the other rows. why this method isn't firing on the rows that aren't initially visible in my DIV?

Forms Data Controls :: Property Of Custom Control In Repeater Is Null On Postback?

Jan 12, 2011

A common problem in repeater controls where you want to display data for update (like a list of user phone numbers that can be updated and submitted back to the database) is where to store the database unique row identifier. So, I created a custom Textbox control that I've added a Data property to. I populate this data property with the unique row id. The problem is that when I post back the list and go through the repeater items the control's data property is null. The custom control looks like this:

[Code]....

The tag in the repeater looks like this:

[Code]....

I have a custom checkbox with the same data property and it works fine. I actually put in the same repeater with the textbox control and the checkbox control have the row id on postback but the textbox did not. Is there some limitation on the textbox control that might be causing this.

Forms Data Controls :: Change From A Gridview To Datalist And Use Of Repeater?

Sep 10, 2009

I am building an ASP.NET page which include a shopping cart, and currently I have a menu page which include a gridview and a dropdown list.

customers can choose a particualr shop from the list of shops that appear and then see the menu for the selected shop, from the menu page, at first for any shop category 1 will be displayed, and customers can then choose category 2, 3, etc and by choosing other categories products related to the selcted category will be displayed.

However now I have found out that I should have used a Datalist with Repeater for the menu page, however what I wondering is that if I do change from gridview to Datalist with repeater, could I still keep the category dropdown list and would the dropdown list still work as it is with the gridview.

Forms Data Controls :: Find Html Anchor Inside Repeater With Dynamic Data And Then Change ID

Nov 5, 2009

I have a master page that uses a repeater to create html anchors for the main navigation menu. I also have some css that controls the display. The anchors are databound from a web.sitemap file.

I also have exposed a property on the master page that specifies which anchor is supposed to be highlighted in the navigation menu. Content forms assign value to this property.

Here are the relevant snippets:

[Code]....

[Code]....

What happens is I successfully match the ActiveMenuSelection property to the item_databound argument, but from there I am a little fuzzy on finding the specific control I want to modify.

Has anyone ever tried something like this?

I know that I could probably use an <asp:Menu /> control, but if there is a solution to the above, that would be better for my purposes.

Forms Data Controls :: Change Stored Procedure When Dropdown Item Is Selected And Show Repeater?

Jul 9, 2010

I have one repeater on page which has his own sql data source. I've placed 2 dropdown lists on the page. The repeater has jQuery DataTable plugin. With 2 dropdownlist I wish to change the sql stored procedures so when each will be selected the data in repeater will change. When user select the first there will be only data (users) according to selected item and in the second the same. I wrote 2 simple functions for changing stored procedure of repeater and rebiding it. Everything works but when I try the second one and then the first I always get warning about error "Procedure or function .... has too many arguments specified".

I think that when I select the first one the second function is still called although I don't call it.

Populate Literal With Checkboxlist Value Without Postback?

Sep 24, 2009

I have a checkboxlist that I databind with values. Each time a user selects one of the values, I want to have that value added to a literal to show them what they have alreeady selected. If I use a postback, it works fine, but the checkboxlist returns to the top of the list every time, rather than staying where it was last checked.

Right now on the postback I populate the literal with the selections.

What do I need to do in order to get the checkboxlist to stay where it left off and still get the value into the literal? Is there something within the checkboxlist itself?

State Management :: Literal Losing Value On PostBack?

Dec 13, 2010

Never had this happen before. I just upgraded my site from 3.5 to 4.0. Here's the scenario:

1.) I have a literal on a web form, in an UpdatePanel.

2.) On PostBack, the Literal's "Text" property loses it's value. The ViewState is enabled throughout the page. Further, I changed the Literal to a label and it also has this problem. The TextBox's appear to keep their values.

3.) If I remove all of the Ajax controls (which currently is just the UpdatePanel and the ScriptManager) then the Literal control keeps it's value through PostBacks.

4.) There is no client side JavaScript where I'm manually changing the values of these controls. They are only editted in the server side events.

I have read that setting the AutomaticDataBind property in the web.config could remedy this but I can't find any documentation on it and I don't know where to put it in the web.config to even try it.

The above does not throw any compile errors but it does not work correctly.

accParent produces 6 headings, the first with 3 children, the second with 3 children, the other four each with one child.

The accordion hides the Times and Locations (showme panel) from the first accChild item in the first heading, which is incorrect as there are records to display, but does not hide the panel from the accChild of the last two headings, where there isn't any data to display.

Forms Data Controls :: ImageButton Inside A Repeater That Is In Another Repeater & Events?

Jan 18, 2010

I have a user control that displays a shopping cart in an ecommerce application.

The main cart display is a repeater that renders as a html table. In one of those table columns, there is another repeater to display people associated with the products int he cart (it's a repeater in case there is a line item >1 with multiple people).

I've added an ImageButton that I want to use to change the person associated with the item. At first, when I'd click on it I was getting this error:

Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

So as an experiment I disabled EventValidation on the page (not the control it's self) and now I do not get an error, but I also do not ever hit the breakpoint I set in the innermost repeater's ItemCommand event.

So I wonder how I might do this without disabling EventValidation, because this control will show up on multiple pages and we don't want to edit them all. Also, I'll need to know not only the repeater containing the control's row that the event came from but also the row index of the repeater containg this one. Is this possible?

C# - Repeater Within Repeater (ajax Based Web App) - Cannot Use Any Postback Methods

Jun 23, 2010

For the solution, I cannot use any postback methods, because this is all working through ajax. The solution need to be implemented in the asp.net code. I have a List<WebPage> that contains a list of Links (List<Link>) and I need for all the links to bind repetitive information such as page title, id, url. Here is my current repeater.

<div id="result">
<asp:Repeater runat="server" id="results">
<Itemtemplate>
<asp:Repeater runat="server" datasource='<%# Eval("Links") %>'>
<Itemtemplate>
<tr class="gradeX odd">
<td><%# Eval("Id") %></td> //property of WebPage (part of results repeater)
<td><%# Eval("Title") %></td> //property of WebPage (part of results repeater)
<td><%# Eval("Url") %></td> //property of WebPage (part of results repeater)
<td><%# Eval("URL") %></td>//Property of Link
<td><%# Eval("URLType") %></td> //Property of Link
<td><%# Eval("URLState") %></td> //Property of Link
</tr>
</Itemtemplate>
</asp:Repeater>
</Itemtemplate>
</asp:Repeater>
</div>

of course this doesnt work, how can i do this?

How To Persist The Data From A Repeater After Postback

Jul 1, 2010

I have a repeater that displays financial data and prices for various stocks.

On this page, I also have an "export" button that needs to take the data ~on the screen~ and convert it into a CSV for the user.

The problem is, after I databind my list of "Stock" entities:

List<Stock> stocks = GetStocks()
rptStockList.DataSource = stocks;
rptStockList.DataBind();

The data is not persisted on postback.

Also, the data on this page is constantly being updated via an UpdatePanel and a Timer control (being re-databound each time). Every 30 seconds the prices displayed for the various stocks in the repeater control change.

Now, I have a linkbutton that has a click event method in the code-behind that is supposed to export the ~data on the screen~ for the user. I need to grab the current values for the list of stocks last databound to the repeater. I can't simply go grab the latest values from the database because those will have been changed in the time between the last refresh.

protected void lbtnExportStocks_Click(object sender, EventArgs e)
{
// No longer have the stock data used in the repeater control
ExportStocksToExcel();
}

I know that ASP.NET doesn't persist the datasource for the repeater on post-back but I need to still be able to either re-construct this list of Stock entities so I can send them the CSV or I need persist it in some way.

I don't want to do anything that is too heavy handed in terms of performance because during certain days of the week this application can have some heavy usage.

What is the proper solution to this type of situation? Should I iterate through the Repeater's "Items" collection and reconstruct the Stock entities?

I have links at the top of the page that are the letters A-Z. What I want to do is click on one of the letters, then show only the div IDs that start with that letter. I can't figure out how to do this since I'm dynamically creating the ID names. I had it set up nicely with Javascript and CSS, but the function call was inside the repeater. The layout is changed now, and I don't understand how to make the div ID available outside the repeater.
