I'm trying to program a site so object oriented as I am able to....To do this I found a Paging example on the net.....but written in VB - and I'm programming in C#.In the VB example there is a line:

I have googled this a while now - and what I can figure out is there is missing something.....But I cann't figure out what.
I have a gridview in my page, called "GridView1", and Paging is enabled.I want to create a handler for PageSelectedIndexChanged but i keep getting this error: No overload for 'PageSelectedIndexChanged' matches delegate 'System.EventHandler'
asp:GridView
ID="GridView1"
runat="server"
OnPageIndexChanged="GridView1_PageSelectedIndexChanged"
[code]...
It highlights this bit of code:
<asp:DataList ID="DataList1" runat="server" DataKeyField="uniqueid"
protected void Page_Load(object sender, EventArgs e)
protected void DataList1_Load(object sender, DataListItemEventArgs e)
Label Label1 = (Label)e.Item.FindControl("Label1");
Label Label2 = (Label)e.Item.FindControl("Label2");
Label Label3 = (Label)e.Item.FindControl("Label3");

I'm trying to look up the TypeID for each row of data returned from my sqldatasource that is displayed in a repeater. But I keep getting this error: CS0123: No overload for 'rptSectionExperience_OnDataBinding' matches delegate 'System.EventHandler'I know I've looked up values from a datagrid before and programatically used the data.

I create dynamic radiobuttons and want to add an eventhandler to them. What I have now doesn't work.
[Code]....
I have a eventhandler in code behind of a UserControl.
[Code]....
This one gets called from Page_Init
When i embed it directly into an aspx page it works as intended. But when i add the control to antoher control which is embed into an aspx page. The event suddenly doesn't fire.
aspx->usercontrol->usercontrol.
I have code, where i add ImageButton to table programaticly and I need to assign event handler to this ImageButton. When I write ASP/HTML code, there is attribute OnCommand, but in C#, there is nothing like this. Just CommandName and CommandAttribute.
ImageButton ib = new ImageButton { CommandName = "Edit", CommandArgument = id.ToString(), ImageUrl = "~/Images/icons/paper_pencil_48.png", AlternateText = "Edit document" };
I'm adding a Button to a TableCell dymanically in code-behind and cant get an event handler to work.
Here's some code...
...
TableCell tc = some TableCell....
Button b = new
Button();
b.Text = "Go";
b.Click += new
EventHandler(OnSequenceChanged);
...
protected void OnSequenceChanged(object Sender,
EventArgs Args)
{
}
I set a break at OnSequenceChanged, but it doesnt hit when I click the button. It posts back - Page-Load gets called - but its event handler doesnt get called.
i have create two linkbuttons dynamically:
for (int i = 0; i < 2; i++)
{
LinkButton lb = new LinkButton();
[code]...
On page load I have this:
LinkButton1.Attributes.Add("onclick", "window.open('EditClients.aspx','','height=700,width=600');return false")
I also have an event handler for LinkButton1:
Protected Sub LinkButton1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles LinkButton1.Click
Label8.Visible = True
RefreshButton.Visible = True
End Sub
The problem is the event handler is ignored. Label8 and RefreshButton do not becoem visible when clicking Linkbutton1, but the new window opens fine. How can I make all things happen?
The scenerio is I have a UserControl. This user control will create dynamically ListBoxes if the given List's count > 0. The controls are adding dynamically, there is no problem with adding them, but the event handler is not adding. If I select an item in first listBox, the secondListBox will be added dynamically, and items will add dynamically too. First listBox appears, but the selectedIndexChanged event handler doesn't work. What can be the problem with my code?
EDIT: I tried to add
li.Attributes.Add("onselectedindexchanged","selectedIndexChanged");
or
li.AutoPostBack = true;
but still not firing...
private List<string> myList = new List<string>() { "Serkan", "Kadir" };
private List<string> mySecondList = new List<string>() { "Istanbul", "Ankara" };
protected void Page_Load(object sender, EventArgs e)

A new route to an old problem for me... I'm creating radiobuttonlists and adding them to an update panel dynamically using this code:
[Code]....
I'm wanting to get the selected radio button value whenever a button on the page is pressed, however (and this is my old problem) I cannot retrieve that value. What I'm wanting to try is to add an event that will record the chosen radio button whenever the selected value has changed and store it into an array.
write the custom eventhandler for a radiobuttonlist's SelectedIndexChanged, which was creating dynamically during runtime.

View 3 Repliestrouble with the gridview.First at all, I needed a dropdownlist in my gridview, I got it, but now I would like to add a new column with a linkbutton or link that send me to another page to edit an especific item (users in this case), but when I add the column and use templates to put a linkbutton I cannot add event to every linkbutton :(I do this in:

I have button, which fires an event, that deletes a record from the database. This is the source of the button:

But how can I make a confirm box appear before the deletion?
I was trying to get the callback eventhandler work for me with Dropdown and either of the radio(s). I know the sample of this in asp.net 2.0 where both the contorls are dropdownlists. Please help me to know is it possible?
View 2 RepliesI´m using a Repeater to generate Items out of a Database. Each ReapeaterItem should include an UpdatePanel, because i have to Update the Controls inside the UpdatePanel and do not want to reload the complete page. Inside these dynamically generated UpdatePanels (each RepeaterItem has one) i´m adding up to three Checkboxes dynamically (based on the Database). These Checkboxes need to fire the "CheckedChanged" event, because on some conditions i want to enable/disable/check/uncheck Checkbox1, 2 or 3 based on business logic. ... Hope you got this so far. I´m adding all Controls and have the EventHandler Added. But the generated Code does not reflect the Event Handler. I tried OnItemDataBound, OnItemCreated, PreRender, ... Events to add the Eventhandler too, but i was not able to find the CheckBox-Control with the ID.
I´m totally lost with this and on the way to use Buttons instead of Checkboxes. From what i read so far is that with Buttons i can use the CommandName from the Button and the ItemCommand-Event from the Repeater to get a workaround, but then i need to reflect the "Check" on the Page in some way. btw, every Repeater (8) sits inside an ajaxtoolkit-accordion control. Here i give you some Code:
aspx-Page
<asp:Repeater ID="RepeaterAccordionPane2" runat="server">
<ItemTemplate>
HTML Stuff<%# DataBinder.Eval(Container.DataItem, "Header")%>HTML Stuff<%# DataBinder.Eval(Container.DataItem, "Beschreibung")%></td>
<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode=Conditional>
<ContentTemplate>
</ContentTemplate>
</asp:UpdatePanel>
HTML Stuff
</ItemTemplate>
</asp:Repeater>
Here is the Page_Load Part
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
dvAlleArtikel = new System.Data.DataView(...Database...);
[... some other code here ...]
RepeaterAccordionPane2.DataSource = dvAlleArtikel;
//RepeaterAccordionPane2.ItemCreated +=new RepeaterItemEventHandler(RepeaterAccordionPane2_ItemCreated);
//RepeaterAccordionPane2.PreRender +=new EventHandler(RepeaterAccordionPane2_PreRender);
RepeaterAccordionPane2.DataBind();

I am banging my head with gridview at the moment. There's a problem I just can't get my head around. I'd be very greatful for any advice given. I have a function that creates a DataTable with three columns and four rows. In each of the cells I set the text to a random number through RowDataBound event. I would like to just make the cell clickable and have a code-behind function that gets the position of the cell (column, row) and the value of the cell when the user clicks it.
View 3 Replieshow am I be able to display a text into a customvalidator control, say for example an asterisk symbol (*) for a new entry. If in case that, the inputted value is invalid then, I will place proper prompt text.
View 2 RepliesMy web page uses a number of custom validation controls to check that values have been selected in DropDownList controls. I have written simple Client side scripts and also server side, but the validation control never gets fired. I am performing validation using a button-click that has CausesValidation set to true.
[Code]....
I have two CustomValidators, both of which function in the same way (call a query and check if a particular value is available in the DB), the only difference is the query itself.
Rather than writing the same function definition in the code-behind, I would like to find a way to execute a particular query depending on which CustomValidator called the function (I guess using the CustomValidator's ID) so if I have the follwing:

How can I check in the code behind , which validator called the function "Check"??
i have this ValidationExpression="(d{1,}.{0,2} .{2,})|(.{2,} d{1,}.{0,2})" used in regularexpression validator. I want to use the same one in a customvalidator. But customvalidator does not have option validationexpression. how can i add this in code or in tag.
