i am developing a website in which i have to create dropdownlist at run time ..
no of dropdownlist to create is depends on another dropdownlist's selected value .
My problem is that how can i get the selected value of dropdownlist which i create at runtime .
One more thing i want to tell that all these dropdownlists are in a formiew .
I have creted a checkbox for each column of grid at the top of the header in row created event. I need to check wheather checkbox is checked after button click event.
//Build custom header.
GridView oGridView = (GridView)sender;
GridViewRow oGridViewRow = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Insert);
TableCell oTableCell = new TableCell();
//Add Staff_ID
CheckBox chkStaffID = new CheckBox();
chkStaffID.ID = "chkStaff_ID";
chkStaffID.Text = "Hide";
chkStaffID.CheckedChanged += new System.EventHandler(chkStaffID_CheckedChanged);
chkStaffID.AutoPostBack = true;
oTableCell.Controls.Add(chkStaffID);
oTableCell.ColumnSpan = 1;
oGridViewRow.Cells.Add(oTableCell);
Once i select the checkbox on different columns then after firing the button click event i want to get which checkbox is check and unchecked.

I have a web user control with dynamic LinkButton think an event in which you assign events to them (LinkButton.Click + = new EventHandler (Method)).The problem is that these events do not run, I did test creating and if you run statically.Why is it??I need to be created dynamically at runtime.For Examples :
for (int i = 0; i <= 5; i++)
{
Button boton = new Button();
[code]...
I got few check box (depend on settings) that created during run time, some time the number of check box is 3, sometime is 5. And the check box ID also change based on the settings.
How can I search for ALL these check box and return its ID? I do not want to use javascript.
I'm having problems binding controls at runtime. I've some user controls which need to be bind to the page when one of the dropdownlist selected index changed.
I can able to bind them properly but when if there is any postback event happens I am losing the controls and control values which were created runtime.
How do I avoid binding them again and again.

I 'have' to use IE 6.0.
I have already tried document.getElementbyID for the table and getElementsByTagName adn they are not working.
var curValue = document.getElementById("<%=TableGridView.ClientID%>").rows;
curValue is 1 in IE and 4 in firefox.
I intend to add dropdownlist and Textbox Controls at Runtime as below:
CustomerID
I have a question connected with controls and event handling. Lets say I want to create a LinkButton.
protected void loadLinkButton()
{
ContentPlaceHolder content = (ContentPlaceHolder)this.Master.FindControl("MainContent");
LinkButton lnk = new LinkButton();
lnk.ID = "lnikBtn";
lnk.Text = "LinkButton";
lnk.Click += new System.EventHandler(lnk_Click);
content.Controls.Add(lnk);
}
Here is the event handler:
protected void lnk_Click(object sender, EventArgs e)
{
Label1.Text = "ok!";
}
If I run the loadLinkButton function inside Page_Load everything is ok. But when I try to run the loadLinkButton by clicking simple button, link button is created but event is not handled.
protected void Button1_Click(object sender, EventArgs e)
{
loadLinkButton();
}
I there any way to solve it? Or loadLinkButton must always regenerated on Page_Load, Page_init etc.
How would I transfer the values of an array created at runtime from one page to another? I tried using Response.Redirect because single values are getting transferred, but this isn't working properly with the array.
View 1 RepliesIs it possible to add tooltip on dropdownlist items?
If yes, I want to implement something as below:
While loading dropdownlist I have...(in c#)
Dropdown.DatavalueField = "request_Category_ID";
Dropdown.DataTextField = "request_Category_Name";
Now, I want to add request_Category_Description as a tooltip on each items in Dropdownlist.
I have created some dropdownlists in the SelectedIndexChanged from another dropdownlist in a PlaceHolder1. Now I want to retrieve the value from the created dropdownlist
in the Button_Click1 method but I don't understand how I can achieve this.
The list items in lijst seem to be empty so I get an System.NullReferenceException; on line

I have a table and 7 column name.
I bind the 7 column name in one dropdownlist.
Now the problem is,how do I extract the data value in a dropdownlist?
For example,
Dropdownlist contain 7 column name
-subject_name
-subject_code
-venue
-time
-seat_no
-admission_no
-subject_id
when I click the subject_name,I want it to appear in a gridview
Example
Math|9.00-10.00|Hall|18|09090J|...
Below is my current codes which I have a problem.
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
SqlConnection conn = new SqlConnection("Data Source= EN\SQLEXPRESS;" + "Initial Catalog=ms;Integrated Security=SSPI");
SqlDataAdapter adapSel;
string mySQL = "SELECT '" + dd_list.SelectedValue+ "' FROM examtimetable ";
adapSel = new SqlDataAdapter(mySQL, conn);
conn.Open();
DataSet dsSel = new DataSet();
adapSel.Fill(dsSel);
GridView1.DataSource = dsSel;
GridView1.DataBind();
conn.Close();
}
Previously I have bind 7 column name in my dropdownlist
protected void Page_Load(object sender, EventArgs e)
{
if (Page.IsPostBack == false)
{
SqlConnection conn = new SqlConnection("Data Source= EN\SQLEXPRESS;" + "Initial Catalog=ms;Integrated Security=SSPI");
SqlCommand sqlCmd = new SqlCommand("select column_name from information_schema.columns where table_name='examtimetable' and COLUMN_NAME not like '%ID'", conn);
conn.Open();
SqlDataReader ds;
ds = sqlCmd.ExecuteReader();
dd_list.Items.Clear();
dd_list.DataSource = ds;
dd_list.DataTextField = "Column_Name";
dd_list.DataValueField = "Column_Name";
dd_list.DataBind();
dd_list.Items.Insert(0, "Select Option");
ds.Close();
conn.Close();
}
}
Currently,below is my code.
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
SqlConnection conn = new SqlConnection("Data Source= E\SQLEXPRESS;" + "Initial Catalog=k;Integrated Security=SSPI");
SqlDataAdapter adapSel;
string mySQL = "select column_name from information_schema.columns where table_name='examtimetable' '" + dd_list + "'";....
I receive an error "Incorrect syntax near 'System.Web.UI.WebControls.DropDownList'."
