I started to programming with asp.net, I have a table with some checkboxes.
The problem is, I can't create static tables, because this action is linked with some parameters. Anyway.. When I click on the First checkbox I want to invert the other checkboxes in this table.
How can I catch this event?

you can try this code
List<CheckBox> lstChckBox;
protected void Page_Load(object sender, EventArgs e)
{
// you can create controls programaticaly or html page, doesnt important
//only you should know controls ID and all controls share same checked event
CheckBox chc1 = new CheckBox();
chc1.CheckedChanged += new EventHandler(chck_CheckedChanged);
CheckBox chc2 = new CheckBox();
chc2.CheckedChanged += new EventHandler(chck_CheckedChanged);
CheckBox chc3 = new CheckBox();
chc3.CheckedChanged += new EventHandler(chck_CheckedChanged);
// Now, you can create a List so event is fired, you can catch which controls checked or not
lstChckBox = new List<CheckBox>();
lstChckBox.Add(chc1);
lstChckBox.Add(chc2);
lstChckBox.Add(chc3);
}
void chck_CheckedChanged(object sender, EventArgs e)
{
CheckBox checkBox = (sender as CheckBox);
foreach (CheckBox item in lstChckBox)
{
if (item != checkBox)
{
item.CheckedChanged -= new EventHandler(chck_CheckedChanged);
item.Checked = !checkBox.Checked;
item.CheckedChanged += new EventHandler(chck_CheckedChanged);
}
}

I created a multiview control with different views. Each views have separate edit buttons which should update the fields only in that view. The edit button is working properly on the first view/tab. But not in the others. I have used update panels in different tables in different views. Still not working. Blow is the code.
Found out hat the code is not able to find any control inside the table content. But why?
<asp:Button Text="Information" BorderStyle="None" ID="Tab1" CssClass="Initial" runat="server" OnClick="Tab1_Click" />
<asp:Button Text="IP Adresses" BorderStyle="None" ID="Tab2" CssClass="Initial" runat="server" OnClick="Tab2_Click" />
<asp:MultiView ID="MainView" runat="server">
<asp:View ID="View1" runat="server">
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<div id="div1" runat="server" >
<table id="tableContentInfo" style="width: 80%;" runat="server"></table>
</div>
</ContentTemplate>
</asp:UpdatePanel>
</asp:View>
<asp:View ID="View2" runat="server">
<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<div id="div2" runat="server" >
<table id="tableContentMake_Model" style="width: 100%;" runat="server"></table>
</div>
</ContentTemplate>
</asp:UpdatePanel>
</asp:View>
</asp:MultiView>
This is the code behind.. the controls inside the views are created dynamically and they are showing properly with data. tableContentMake_Model is the second view id.

I think you can have one Update panel for all the views in common that is above the multi view control.I usally use in that way.Hope that can give the hint to your problem.
Please let me know if your problem solved.
Thanks

I am trying to create a form for courses provided by a University. Based on the no of subjects obtained through a query string, a form gets generated. If the subject has electives, the user has to check a checkbox, which further generates a no of textboxes for subject names. But whenever I check the checkbox of say 2nd subject the textboxes previously displayed for 1st subject disappear.

}
}
so in this code I create a div and I place inside it a label and a Radio Button List however what i want to do is to create an event handler and send a data to it when i call it i call it like this:
Rate.SelectedIndexChanged += new EventHandler(CheckChange("s"));
and this is the event handler:
protected void CheckChange(string s)
{
ScriptManager.RegisterStartupScript(Page, typeof(Page), "", "fun('" + s + "')", true);
}
It give me an error "method name expected" when I send the data like this
any solution?
I am grabbing some records from a database depending on the id number of the page, the amount of records that will display will vary, anywhere to 1 record to 50. I need to take these records then choose which ones I will be modifying, deleting, or won't change at all. I would like it to look like this:
Can't get image to show with stackoverflow image uploader so here: https://dl.dropboxusercontent.com/u/9446763/code/dropdownlist.jpg
I would like the text fields to be disabled if No Change or Remove is selected, and the fields enabled for revising if the option Modify is selected.
Below is what I have so far, the part I am struggling on is the selectedindex change I do not know how to code it so that when Modify is selected in the dropdown box the appropriate textboxes become enabled.

You need to have members in your class that hold references to your DropDownList and other controls that you want to enable/disable.
public class YourClass {
private DropDownList ddl;
private TestBox txa;
private void createControls {
// ...
TextBox txa = new TextBox();
txa.ID = "amtData" + rowcount.ToString();
// ...
DropDownList ddl = new DropDownList();
ddl.Items.Add("No Change");
// ... etc.
}
void ddl_SelectedIndexChanged(object sender, EventArgs e)
{
if (ddl.SelectedIndex == 1)
txa.Enabled = true;
}
}
