I have a Placeholder in which I added a Hyperlink (the hyperlink is an attachment in messaging application) how do I get the hyperlink to go hot when the user put there mouse over it:

I have a formview that has several dropdownlists in the EditItemTemplate. Some of the dropdownlists are added using placeholders. I can add and populate their listitems without any problem. But when I update the record, none of the controls can be found--even though when I look at the page source they are there. I first strated out using asp:ControlParameter in my sqldatasource updateparameters, but even referencing the control as myform$mycontrol did nothing. So then I moved to code behind on the sqldatasource.updating event (code is attached). The only controls I cannot seem to bind to the update are those added via the placeholder.

The item at the dim statement is not an item added using a placeholder and does not get a null reference exception (I used that to prove during debbugging that I wasn't losing my mind)--however, all the items being used to get the parameter values are getting null reference exceptions and are added via placeholders. Here is the code I'm using to set up the dropdownlists:

how to get the value of these controls so they can be used in my update?
I add one or more textbox controls to a repeater itemtemplate during OnItemDataBound.
The textbox controls are instantiated and then added to a placeholder.
My problem is getting the user entered values from those dynamically added textboxes. They do not seem to exist in the repeater items collection.

Can a placeholder control be created dynamically such that you can add controls to it later on?
PlaceHolder ph_grid = new PlaceHolder();
I have a dropdown on page, a place holder and a save button on my form.Now, I am creating a textbox on selectedIndexChanged event of dropdown list and adding it to placeholder. And on button click I want to access the control, but on click event, I find the textbox as null. Here is my code
protected void Dropdownlist1_SelectedIndexChanged(object sender, EventArgs e)
{
if (Dropdownlist1.SelectedValue != string.Empty)
And button Save click event
protected void btnSave_Click(object sender, EventArgs e)
{
TextBox txt = new TextBox();
txt = (TextBox)this.ElementPlaceHolder.FindControl("txtArea");

I am using list view to display the the data but i am getting an error like An item placeholder must be specified on ListView 'ListView1'.

I'm creating an ASP.NET control dynamically based on a value selected in a dropdown; for instance the field can be a textbox or a checkbox (for now), and then it gets added to a placeholder control. However, I'm unsure how to retrieve the value - using the placeholder's FindControl method returns null although I'm specifying the ID when I create the control.
Here's my code:

how to maintain state of placeholder. i have a placeholder in which i add many image controls dynamically but when my page get refresh all controls from placeholder gets removed from it. the enableViewstate of placeholder is set to true.
View 3 RepliesI am outputting the content of a page from a subroutine. The weird thing is, the code behind is writing this to my aspx page. <asp:Hyperlink ID="HyperLink1" runat="server" CssClass="HoverMenuText">more</asp:HyperLink>
When the page is viewed live, the hyperlink is not a hyperlink because using the browser to "View Source", the html shows the exact same line! It wasn't converted to the format like "<a id="ctl00_ContentPlaceHolder1_HyperLinkHover">HoverMenuTest</a>" So for some reason, the server is not converting this asp control to an html control. Any ideas why it wouldn't do that?
I have a GridView control which contains a custom <pagertemplate> with a <asp:PlaceHolder runat="server" ID="plcPages"> control. The .aspx.cs file contains the following code:
protected void Page_Load(object sender, EventArgs e) {
... {Other Code} ...
GridViewRow pagerRow = GridView1.BottomPagerRow;
PlaceHolder PagePlc = (PlaceHolder)pagerRow.Cells[0].FindControl("plcPages");
Button btnPage;
int iPageNum;
for (int i = 0; i < GridView1.PageCount; i++) { iPageNum = i + 1;
btnPage = new Button(); btnPage.ID = "btnPage" + iPageNum.ToString();
btnPage.CommandName = "Page"; btnPage.CommandArgument = iPageNum.ToString();
btnPage.Text = " " + iPageNum.ToString() + " ";
PagePlc.Controls.Add(btnPage); } }
Everything works fine the first time the page is displayed. But, when I click any pager button, including the Next and Prev command buttons that are not part of the PlaceHolder, the contents of the PlaceHolder are never re-displayed. I know from searching other posts that the PlaceHolder contents are lost during the trip to the server, but I am already recreating them every time the page is loaded. They are just never being shown again. I've spent the last two days playing with ViewState And every other combination.

I'm using VWD with a database back end. I have a list of teams which are marked off by league, level, division, teamid and then using gridview for the list of players per teams.I've got the drop downs working correctly but running into a little snag and that is on the auto postback.When I only have one option come up in a list, i obviously don't change that list and thus it doesn't change the next drop down because there is no post back. is there a way to use a "header" value?

I have a repeater control having columns in it.When I bind the control to a data source then some of the columns become empty when there is no data associated with it.I want to hide the column if there is no data associated with it.I was trying to implement a solution given in this thread:

View 4 RepliesI have data in mydatabase. My AnswerText in the database is test1,test2,test3 While retrieving it is displaying as test3,test1,test2. I am using the below code to display the data.
Dictionary<string, string> dicKeyValues = new Dictionary<string, string>();
for (int i = 0; i < cnstsData.Answer.Count; i++)
{
dicKeyValues.Add(AnswerText, AnswerImage);
}
DataList.DataSource = dicKeyValues;
DataList.DataBind();
I want to display the AnswetText as test1,test2,test3. Basically i want the same order which i added to the database while retrieving also.
I've got a datatable in a dataset which contains 44 rows. I can iterate through the rows and add the data to a placeholder - it's all there. However, if I bind a control (say a gridview or dropdownlist) to the datatable, all I get is one record (from the "middle" of the table). I get the same result when I create a dataview of the table - one row.
View 4 RepliesMy code is below. I can add messages for row deleted and row updated fine, but the e.exception doesn't exist for row-created. My add-row 'success' message doesn't work properly because it doesn't allow the other messages to then overwrite the label.text for some reason.
