I have a link button inside a repeater. How would I directly call the serverside (ItemCommand) method during postback. I want to skip the page_load. The wierd thing happening is, if I put (!Postback) it doesn't execute other methods on postback but it does if I don't set the !postback condition. I have repeater inside a updatepanel in UserControl.
i am unable to change the selectedindex property to 0 it is coming as -1 only and the code wat i am using is
if (lstintellisense.SelectedIndex.ToString() == "-1") { lstintellisense.SelectedIndex = 0; }
after making 0 also its remaining as -1 only and i am getting exception as InvalidArgument=Value of '0' is not valid for 'SelectedIndex'. Parameter name: SelectedIndex
I have actually resolved my problem but I want to understand why. The scenario I have is an input for logging in on my Default.aspx page. When the user logs in the page refreshes and the login box changes to display a logout box using:
loginBox.visible = false
logoutBox.visible = true
My question is about the positioning of this code. I had my code validate the users input when the btnLogin is clicked. I then had those two lines above under PageLoad but this did not work. The user would log in but would have to refresh the page to update the boxes. Instead I had to place those two lines of code in the btnLogin Clicked area, at the same time as the user is validated.
It was always my understanding that when something on the page is clicked/activated the entire page is reloaded, but this appears not to be the case otherwise the PageLoad area should have worked.
This is my first web page ever and I can't seem to find the correct way to get the selected index from a dropdown list. I don't need the selected index until the user presses the submit button. I've been testing everything I've found on the subject, but nothing is working.
I don't want the drop-down box to reset when the selection is made, which is what happens if I use postback=true or any selected index changed events. And, I still get an index of 0.
I am trying to extract month and year from database and show it as selected in the dropdown. Ex: Month and year, consider 2 and 2013. I want the dropdown expmonth to show Febraury and expyear as 2013 when the page is loaded. When i tried the below code, it did not show me 2 and 2013 instead showed Jan and 2010 which is default.
I am passing the values obtained from ddlSubGroup and ddlPageNumbers to a datasource as parameter (Actually to a pageddata ) , on which i create a DataList.
The page is working fine actually but the problem is like the following,</p>
Considering that all dropdown are selected as following :
When i change ddlSubGroup to another one , ddlPageNumbers is populated depending on the number of items divided by 20 ( The datalist is paged by 20 items per time)
then i change the ddlSubGroup(RUBBER PARTS in this example for example to BodyParts , so the dropdown values becomes like :
[code]....
At this point Body PARTS also has page numbers like 1,2,3,4 etc but, it still remains as 2 , however i need the page number to reset back to 1.
Is there any way to do this , and where should i place the code exactly ( which event ) ?

I cannot change the text in the drop menus. It was originally "Select a General Market", and "Select a Market". I have changed them and the changes due not take effect. I can change the labels, but not the default text inside the dropdown list. Is this something that needs to be changed elsewhere?
<asp:label id="lblSelectGenMark" runat="server">Select a market: </asp:label> <asp:dropdownlist id="ddlGreaterMarket" runat="server"> <asp:ListItem Value="None">Select a market</asp:ListItem> </asp:dropdownlist> <asp:label id="lblSelectMark" runat="server">Select a region:</asp:label> <asp:dropdownlist id="ddlMarket" runat="server"> <asp:ListItem Value="None">Select a region</asp:ListItem> </asp:dropdownlist> <asp:button id="Button1" runat="server" Text="Filter Scores"></asp:button></P>

i have two dropdownlist, second dropdown populates based on value selected in first dropdown.
Parentdropdown is working fine and second dropdown is also popualting correctly. But when i select value from second dropdown and click on submit button it resets to first value i.e though i have chosen 3rd value from dropdown it resets to first value.This happens when autopostback is not thr.
