I'm attempting to create a update form that will pull information from my database. I'm a little confused on how to get the information into the textboxes on my form. First I have my form:
[Code]....
This is where I'm getting stuck. I'm not certain what code I need or if what I have is correct. Is there an example what my next step(s) are? I would think that I need to set a variable to hold the data, maybe something like txtRace = Trim(GetString(0)???

I'm coding a report page.In this page,there are two date fields for user to filter the date and the GridView is filled depending on these dates in the CodeBehind (When user click the button view).Now I want toimplement a paging/sorting feature for this GridView.I've researched and see there are default paging for GridView which is not very efficient (my report table may have thousands of records) and custom paging but this requires using ObjectDataSource (which I don't use).Thus anyone can recommend me some approaches that are best used in this situation?

I am having a problem with disabling DropDownList based on the chice of 1st DropDownList, there is no post back occuring, and it is a template based web app here is the current code:
<script type="text/javascript">
$(function() { var dropDownList1 = $('#<%= ddlUserType.ClientID %>');
var dropDownList2 = $('#<%= ddlMember.ClientID %>'); dropDownList1.change(function(e) {
if ( jQuery("#ddlUserType").val() != "ETOC") dropDownList2.removeAttr('disabled'); e.preventDefault();
else
dropDownList2.removeAttr('enabled'); e.preventDefault(); }
} );
</script>
what is happening now is page is blank and if I remove the above code everything shows, where I am going wrong. here is the plain and final javascript code which worked:
<script language="javascript">
function CheckDropDownState(lstbox)
{
if (lstbox.selectedIndex == 3) { document.forms[0].ddlMember.disabled = 1; }
else { document.forms[0].ddlMember.disabled = 0; }
}
</script>
and thew .aspx code: <asp:dropdownlist id="ddlUserType" runat="server" onclick="CheckDropDownState(this);"></asp:dropdownlist>

I am binding months to a list 0-13 items default selection is 0 months duration, and years 0-8 items and 0 years is the default selection.As I know there are always going to be 12 months in a year, I could use selectedvalue or selectedindex without any perceived problem. Is there a reason why I should not use either/or of the two properties to select a list item?

I am a beginner in Dot net Domain.Presently Im creating a web portal for one of our client.In my portal i have displayed the News headline and a button for details in a Grid view. when i click on the button it has to show the detailed news from DB in another grid view. I have done a code on it.,but it shows some error.I have displayed the code below.
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType != DataControlRowType.Header && e.Row.RowType != DataControlRowType.Footer && e.Row.RowType != DataControlRowType.Pager)

Button btn = (Button)e.Row.FindControl("Button12");
btn.CommandArgument = e.Row.RowIndex.ToString();

}
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "newsbtn")
{
int index = int.Parse(e.CommandArgument.ToString());
string key = GridView2.DataKeys[index].Value.ToString();
SqlDataAdapter da = new SqlDataAdapter("select **img,news,detail** from News where news=@n", connect.con());
da.SelectCommand.Parameters.AddWithValue("@n", key);

My Listview control contains 4 columns and 30 rows.I can retrieve the row number by using:
//get row of listview item
ListViewDataItem item1 = e.Item as ListViewDataItem;
int findMe = item1.DisplayIndex;
How do I then get values from one or all 4 columns?I was trying:
this.lblReponseRoute.Text = item1.FindControl("routenameLabel").ID.ToString();
UPDATE1:The final solution is:
//get row of listview item
ListViewDataItem item1 = e.Item as ListViewDataItem;
int findMe = item1.DisplayIndex;
//find label value var routeLabel = (Label)ListView1.Items[findMe].FindControl("routenameLabel");
this.lblReponseRoute.Text = routeLabel.Text;

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.

I have an update page with radiobutton "Alternate Addresses". If the radiobutton has "Yes" value, There would be altenate addresses for client. If radiobutton has "No" value, there won't be any alternate addresses. In update page, if supplier changes radiobutton value from "Yes" to "No" and clicks asp:Button "Update", all alternate addresses will be deleted. I want to show a confirm messagebox on Update button click. But i am not being able to retrieve radiobutton selected value in javascript.
var list = document.getElementById("radios"); //Client ID of the radiolist
var inputs = list.getElementsByTagName("input");
var selected;
for (var i = 0; i < inputs.length; i++)
{
if (inputs[i].checked)
{
selected = inputs[i];
break;
}
This code works fine with html buttons. But I want code for asp:Button onClientClick.
