I have two tables. 1st contain topic and its id. 2nd contain topic name,its category and category list.
I want to display using asp .net datalist and vb script like the following
topic 1
Category 1
categorylist 1 of category 1
categorylist 2 of category 1
Category 2
categorylist 1 of category 2
categorylist 2 of category 2
topic 2
Category 1
categorylist 1 of category 1
categorylist 2 of category 1
Category 2
categorylist 1 of category 2
categorylist 2 of category 2
Also, i have tried displaying only Category 1, 2 .. which are Link button. When I click these button it shows category list. So here I am facing aproblem that everytime i click these buttons it refreshes my page which is very annoying.

I have 3 drop downs in a details view (populated from a gridview) during insert mode.
Dropdown 1
Dropdown 2 --> Based on drop down one
Dropdown 3 --> Based on drop down two
I am curious of how to handle the autopostback to update 2 and 3 since they are part of the detailsview, there isn't a selected_index_changed event.
I am ok with adding items to them on page load, just not for cascading of them...

I have three identical procedures that are all used to open the contents of a GridView into Excel. One was working fine but the other two were getting a 'RegisterForEventValidation can only be called during Render();' error when attempting to run the form.RenderControl(html) command. The only difference I saw was that the one that was working had the allowsorting value set to 'False' where the other two were set to 'True'. I set the other two to false and they worked. So what is going on here? Why would this cause the error; is the GridView somehow doing a post back and loosing settings when this value is set?

I need to process surveys. I have modelled them in SQLServer, just need to generate the forms to input it.I have nested SqlDataSource/DataLists. The outer gets the questions and the inner gets the various options as a plain HTML radio buttons. I can't use ASP.NET radio buttons because of a bug with them inside itemtemplates not mutually exclusive http://support.microsoft.com/default.aspx?scid=kb;en-us;316495Anyway, so now I need to know the which radio buttons were selected so I can insert the values in the database. What is the best way of doing it?

I have a GridView control that has an ItemTemplate that contains an HTML radio button. In my code behind I am querying a database, retrieving a column of values, and then binding the list to the GridView. My problem is that the radio button that I select is not being persisted on post back. I have tried using an ASP RadioButton rather than an HTML control, but when I do that all of the radio button can be selected at the same time (i.e. like check boxes). how to persist the radio button that is selected in this scenario?

I have a text box inside a update panel. With the onTextChanged events, I have a post back set in "True" to show the customer Name and email when I type in the customer ID in the text box. I want to have it show when we leave or Tab out of the text box. Now is working , but only afte I click the submit button. Does anyone know how to code the following in order to make it work right away when we Tab out of the text box.
protected void txtBDID_TextChanged(object sender,
EventArgs e)
{
}

I have 3 textboxes , 1 dropdown , 1 Button and 1 gridview .
Textboxes ID are :ACode , ADesc , ASeq
DropDown ID is :CPhase
Button ID is :AddRowBTN
GridView ID is :PhasesTempGrid
Now whats the story is ?After adding some data into textboxes , when a user clicks ADDRow BTN , that data gets saved into datatable , then that datatable gets binded to gridview and it shows my textboxes data in it .
What i want to achieve ?In my gridview i am use templateField and inside that template field there are textboxes ( Let the users edit the row without clicking any button ) .
Take an example of dummy data and problem persisting in there :for e.g i put some data in textboxes :ACode = "ABCD"ADesc = "EFGH"ASeq = "HIJK"Then i click Add BTN , it saves the data in datatable and show in gridview , now if i do this in gridview :ACode = "Edited ABCD"ADesc = "Edited EFGH too"ASeq = "WoW There"Then i click Add BTN , it removes the edited record in gridview and shows original data which had came earlier from textboxes :ACode = "ABCD"ADesc = "EFGH"ASeq = "HIJK"I don't want that to be done ... Simple is that user can enter data from textboxes , click the btn to submit into grid then he can edit the data like he want ... data must not get flashed , here's my coding i have done so far :
public void AddNewData()
{
var dt = new DataTable();
if (ViewState["myDatatable"] != null)
{
dt = (DataTable) ViewState["myDatatable"];
}

I have a big form in which i have almost 10 update panels. some are having updatemode = conditional and others are always. Now by default when that page is opened i only show one dropdownlist.When that project dropdownlist (from which i populate the rest of the elements in my page) value is changed by user it takes long time to load the other elements. Also the other gridview which is also surrounded by update panel and mode in conditional takes long time to show edititemtemplate controls in edit mode.
I am unable to trace the reason behing delay. Few days ago it was working fine and fast but now it is slow.

Being new to ASP.NET I have run into trouble building my own Whack-a-mole program. I think my problem comes from using Buttons, which by themselves send post backs to the server, making the software unusable. The looks are in place, making new buttons show up in the grid, in different places by random. However, when a button is pushed - the score doesn't change (which I feel is strange).
Not so strange is that the Button doesn't work since it sends post back to the server - reloading the UpdatePanel. I think I should use a different controller like the CheckBox and style it hard using CSS (which isn't a problem). Is this the correct way to go, or should I make use of JavaScript AJAX instead?
Note to self: This technique shouldn't be used in a public application since it put too much unwanted pressure on the web server.

I have an Ajaxable application which has some UpdateProgress for each postBack events.
I want to display another Indicator in my SiteMapPath bar which shows a post back is happening no matter what.
For example when user clicks on a button an UpdateProgress display an Indicator Image in central part of application. I want to display another image ( for every postbacks not only for one) in top of application toolbar.
Currently I use a simple Flag out ther and I want to use an indicator instead of that flag when ever a postback happens
