Ihave the following code and would like to be able to control the layout of the textboxes and labels so they arent just in a long column. Right now everything works and controls are added, but they are added in 1 column which if you chose 32 from the dropdown the page becomes very long.. so would like to maybe wrap them across 3 columns so that each has at least 10 per column.

I'm adding a serires of asp:literal and asp:textbox controls to a panel in code as below (the eventual aim being to add only some of the controls depending on the user):

How can I control how the panel is rendered, preferably without having to create a custom control?
I have a problem with the layout of my datalist. Everything works except for the layout of the datalist. It's currently display 2 columns in a table layout. From the looks of it, when it switches over to the second column my format gets messed up and I mean there are random gaps in certain areas. Is there a way to fix this?
Here's my Datalist control:

I insert into asp.net mvc views C# logic that manages layout like the following:
[code]....
I try to minimize <% %> code placing "{" symbol on the same line as it's condition (java-style). Html layout looks more clear to me after that.
Do you apply C# formatting rules to <% %> html injections "}" should be on a new line or manage layout in different way?
I am creating a survey page that has a list of questions and answers that can be radiobuttonlists, checkboxlists or textboxes. These controls are added dynamically to a Repeater in its ItemDataBound event using Controls.Add.
I've managed to render the page ok but when I submit the form and iterate over the controls in the repeater to get the selectedvalues of the radiobuttons and textbox values, FindControl returns null. What do I need to do to get get the selected values? I've tried iterating over the RepeaterItems but that returned null too. I've tried different types of FindControl but it never resolves the control types.
It works if I add a declarative DataBinder in the Repeater like this
<asp:Repeater ID="rptSurvey" runat="server" Visible="true" EnableViewState="true" >
<ItemTemplate>
<%# DataBinder.Eval(Container.DataItem, "Question") %>
</ItemTemplate>
</asp:Repeater>
However, I want want to dynamically add the controls but in doing this i cant get the selectedvalues when submitting. This is tha main structure of my code...

I have a page that has customer information. I have a requirement to be able to add multiple points of contacts to a contact, so I want to dynamically be able to add a block of label/text boxes with a save/delete button attached like so for each PoC:
How best to do this? I could put a div on the page with a runat="server" and add controls I guess? Not really sure how I lay them out that way correctly though.
In My page i have a ajax Combolist Box in which if i select any no it generates some controls

I have a C# web application that dynamically adds user controls to the default page for whatever "mode" the application is in. The problem is that it is not persisting these across postbacks. How do I persist these across postbacks and keep the content of the controls that are in the user control?
For instance, say I have a user control that creates a new tour record. The user clicks on the Tour item from the menu on the default page, it dynamically loads the tours user control. The user then fills out the form in the tours user control and clicks save. This is where the problem happens. When the postback occurs, the web application has no idea that the new tours user control was ever loaded. So, no save takes place because the Save button's click event never even gets fired.
I have created listof gridview table cells dynamically.
Each cell is having different gridview.
As Gridviews are having different no of rows, they are not alligned properly.
I want to allignment property to top of the cell.
I am working on a page where user controls are dynamically added to the page and refreshed with a timer in an updatepanel.
Since I already coded dynamic user control loading into the page, I would also like to implement *some* form of dynamic layout method for those controls. I was thinking coordinate values.
I have used Top and Left properties on panels before to achieve this functionality in my windows forms applications but since this is a web application things are different.
I realize I can do the whole "absolute positioning layout model" override in Visual Studio but as far as I know this only benefits me at design time. Is there a way to programatically trigger that behavior?
I looked at the silverlight Canvas and how you can pass offset values in with your controls. Something like that would be great, but this isn't Silverlight, lol. I also considered a web method to return globs of html tags to fill the area between these controls.
This is a page that would be reused over and over from client to client so this is why I would like to get this dynamic layout working. It would save me much effort later on.
How to maintain view state for the dynamically added html controls to a table using javascript(Below is the javascript which I am using to add HTML Controls Dynamically"). Because during the postbacks if I found any error while validating the data present in the dynamically added html controls, the controls are loosing their state and again I need to start adding rows and add data.

I have ONE <asp:Button ID="btnAddUC" runat="server" ......./> and ONE <asp:Table ID="tblUC" runat="server"...> on my page. User clicks on btnAddUC, user control is added to the page [user can add 'n' user controls to the page]. here I have no problem, adding user controls to the page on user clicks.
My user control has ONE <asp:DropDownList ID="ddlItems" runat="server" ......./> and ONE <asp:CheckBoxList ID="chkItems" runat="server"..../>. I am exposing "ddlItems" by public method, "chkItems" is not exposed. "chkItems" is binded on SelectedIndexChanged event of "ddlItems".
Execution scenario:
User adds user control to the page, select item from the "ddlItems" ( Note: "ddlItems" is exposed by public property ) , "chkItems" is populated ( using ddlItems.SelectedItem.Value ) . User checks some checkboxes in "chkItems" and then decide to add one more user control. When the second user control is added to the page, checkboxes in the first usercontrol lose their state and apeears unchecked (NOTE: user checked some checkboxes and then added another user control).
I want to put checked beckboxes index in session ( Before another control is added, which event I should use, because at LOAD event there is nothing).
I was able to restict SelectedIndexChanged event to only that user control whcih generated it (checking _EVENTTARGET)
I'm dynamically adding a DropDownList to the GridView in edit mode and I have set the TextBox Visibility to False. In edit mode I can see the DropDownList and I'm able to select an Item from the DropDownList but not able to access the SelectedValue in RowUpdating Event. How to get the selectedvalue of this DropDownList?
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow And (e.Row.RowState And DataControlRowState.Edit) > 0 Then
Dim ddl as DropDownList
FillStateList(ddl)
e.Row.Cells(4).Controls.Add(ddl)
ddl is the DropDownList that is added dynamically. And the default Textbox that is in the Edit mode is set to invisible. So there are actually two controls in the same cell in edit mode(TextBox is invisible).
DirectCast(Gridview1.Rows(e.RowIndex).FindControl("ddl"),DropDownList).SelectedValue
If I use the above statement I'm getting NullException.This is Probably because its a BoundField. Is there a way I can access the DropDownList 'ddl' SelectedValue?

I am adding linkbutton dynamically (actually above snippet tells what I am actually doing, in reality TableRow and TableCell are added dynamiccally). My problem is, I am not setting height of linkbuttuon which will added dynamically. I have no idea what text I have to add to linkbutton.
What I want, after all the link buttons are added, iterate through each added lin button, get the height of each linkbutton, store the max height, then re-iterate throgh the link buttons and set the height of each link button to max height.

View 14 RepliesI am adding table rows dynamically, after I return from a post back, these rows disappear.
Is there a way to preserve these rows and add them back on page load?
I have a page with a table and two button with the names (Submit and Add Rows) When I click on Add Row a new row will be added to a page(This is achieved using javascript), when I click on submit button I will be doing server side validation. If I found any error the error will be displayed on the page. During this process the controls which were added by me were loosing its state. As a result I need to add the rows once again and need to fill the data and click on submit button. Can any one let me know how to avoid this and see that the controls donot loose their states. So that there is no need for me to create rows once again if any validation fails on the server side.

I have to dynamically create controls and add them to a table. In a button click I need to find the value entered for that control. The control ids are also dynamic. Below is the code I tried.

the problem is that i m getting the rowcount=0 of the table tblUdf inside which i added the table rows and controls inside the table cells.
how to get the control values of the dynamically added controls.
I am just trying to add some dynamic controls to the SimpleQueryControl (which of course is a kind of Web Control and inherits all the methods accordingly). I dont know how to get the values of Child controls which I have added dynamically.

I'm adding a dynamically built set of checkboxes to an asp.net page from the code behind with something like this in a recursive fashion:
pnlPageAccessList.Controls.Add(myCheckboxControl);
The controls show up fine on the page, but they don't show up when I view source, nor can I access them from the code behind.If I add the controls in the on_init method, they work. But I have some business rules driving changes to the list of controls itself that require I fire the add method elsewhere. Has anyone seen this before? I'm away from work so I can't copy the exact code.
I have two terrible ideas for how to get it working. One involves some jQuery and a set of hidden controls holding a big array of integers; the other is run the method on_init AND on my other events so the controls at least show up. Both smell like ugly hacks.
I am having trouble getting the input values of dynamically created controls in a ListView.
