Use CommandArgument Property With LinkButton Inside Repeater?
Oct 15, 2010
The link button only sets some value as true and does nothing else. When I run the code the LinkButton's event just won't fire! In my aspx page I got this LinkButton inside of a repeater with CommandName="SetDefault", some ID, runat property. That's it. In my code, inside of myRepeater_Itemcommand(), I got this
if (e.CommandName == "SetDefault")
{
Users obj = new Users();
obj.IsDefault = true;
}
[EDIT] I resolved it myself. It was a silly mistake. "l" was missing from "SetDefault" in my aspx page.

I'm doing a webpage with a search that brings a lot of information from MSSQL. What I did is a stored procedure that return only the page to be seen on the website. Right now I'm working on the paging as I need to show something similar than google. If you are at page 1 they show first 10 pages and if you are at page 19 they show since page 9 to 28. I think the best option to show the page numbers is using a linkbutton inside a repeater. The problem that I have now is that I do not know the best way to take the page number at postback.
Doing a quick sample I assigned an ArrayList to repeater.datasource:
<asp:Repeater ID="Repeater2" runat="server">
<ItemTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" CommandArgument="<%# Container.DataItem %>"><%# Container.DataItem %></asp:LinkButton>
</ItemTemplate>
</asp:Repeater>
<asp:LinkButton ID="LinkButton2" runat="server" CommandArgument="4654">Test #1</asp:LinkButton>
At my Default.aspx.cs file I have the next code
protected void Page_Load(object sender, EventArgs e)
{
if (this.IsPostBack)
{
string x = LinkButton2.CommandArgument;
//string y = LinkButton1.CommandArgument;
//I know this line will not work since the Linkbutton1 is inside the Repeater.
}
What Shall I do to make it works? Does anyone has a better solution for this paging?

I am brand new (like 2 weeks) to ASP.NET and VB.
I have a series of linkbuttons that are generated dynamically inside a repeater.
I need the background color of the selected linkButton to change and remain a new color when clicked. I thought that the ItemCommand property of the repeater would do the trick, but it doesn't.
Here is the code for the repeater:

I have a repeater. This gets bound to a data set which contains (amongst others) a field called EntityType and a field called ID. An Entity Type might be "Person" and there might be several categories of "Person". The ID field identifies that category. So there might be a "Person" type 1, a "Person" type 2 and so on. The Entity Type and ID therefore make up a compound primary key.
Nested in each row of the repeater I have a grid view which get populated as a result of clicking an "expand" button in the repeater row. Each row in the GridView represents an "Entity". So "Peter" who's own ID might be, say 59 might be a "Person" of Type 1. So Peter really has a three column primary key consisting of the EntityType and ID field's from the repeater's dataset and the ID from gridview's dataset.
So in order to query the database and fully retrieve Peter, I need that whole primary key. I know how to get the ID from the GridView's dataset, I set Eval("ID") as the CommandArgument for the gridview's button and then consume it in the event. But I don't know how to get at the EntityType or the ID from the Repeater's dataset. How can I do that?
Here's my code at the moment:-
asp Code:
<asp:Repeater ID="ChildClassesRepeater" runat="server" OnItemCommand="ChildClassesRepeater_ItemCommand" Visible ="false" >
<ItemTemplate> <tr> <td> <%# DataBinder.Eval(Container.DataItem, "EntityType")%> </td> <td>
<%# DataBinder.Eval(Container.DataItem, "Class")%> </td> <td>
[Code] ....
I'm thinking the easiest thing to do is put the EntityType and parent ID on the Command Argument where it currently reads IDontKnowWhatGoesHere but I can't work out how to get at them.
Alternatively, is there a way I can get at them in the event handler? I think not but I'm not sure.
I could have the query for the grid view return the parent columns, that would allow me to eval them in the same way as I am the entity ID. That feels like I'm reading redundant data, though, as it's already there in the client - if I could just get at it.

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?

what changed do I need to make to my code for it to achieve what I'm after.
At the moment I am getting a "cannot cast to type" error message with the below code.
I have also tried calling the ItemDataBound method in with the parent repeater tags and had no errors but when I clicked on the button it would just move back to the top of the page and would not hide or show any data. Also I have made the div style to none but the first record still shows its child but the rest don't.

I am having trouble with the postbacks that are fired within my updatepanel by the linkbuttons. Here is the structure of my page: UpdatePanelMultiViewView1/View1View2RepeaterLinkButtons being generated here /Repeater/View2/MultiView/UpdatePanel. Here is my link button code
<asp:LinkButton ID="lnkSelect" runat="server" OnClick="SelectOrganization" CommandName="OrgID">SELECT</asp:LinkButton>
Whenever I click on any of the LinkButtons that are generated, it does a Postback in the UpdatePanel. But the OnClick function is not being called. It just does the void Page_Load() function. That's it. The controls in my other views work fine, but I'm having trouble with these controls. I think it has to do with them being generated by the Repeater.

I'm trying to use PostBackUrl on my asp.net form (insert mode) to go back to previous page. I'm hoping to use Request.UrlReferrer.AbsoluteURL or similar.The difficulty I have is how to assign value to link button (called InsertButton) property "PostBackURL".
Some examples show simply InsertButton.PostBackUrl = Request.UrlReferrer.AbsoluteURL but it my case it doesn't recognize the control. I'm using VS 2010 with asp.net 4.0

I need to have a Repeater with the letters of the Alphabet, when the letter is clicked on it returns all the "names" that start with the corresponding letter in a gridview.
I have got a basic repeater below working but when I tried to change it to a LinkButton I seem to have problems with the CommandArgument.
<asp:Repeater runat="server" >
<ItemTemplate>
<%# Container.DataItem %>[code]...
I have seen some close examples of this in C# but I need it in VB and the converter I use says incomplete snytax.
