I am working on a project and I need to use Master/Details view, the problem is everything works fine except when I place the Master (gridview) and Details(FromView) in different content holder.

I have a master page that divides the main content into two areas. There are two asp:ContentPlaceHolder controls in the body section of the master page with IDs cphMain and cphSideBar respectively.
One of the corresponding content pages has a control in cphMain that needs to refer to a control in cphSideBar. Specifically, a SqlDataSource in cphMain references a TextBox in cphSideBar to use as a parameter in the select command. When the content page loads the following run-time error occurs:
Could not find control 'TextBox1' in ControlParameter 'date_con'.
Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
[code]....
I kinda know what the problem is... ASP.NET does not like the fact that the SqlDataSource and TextBox are in different asp:Content controls within the content page.
As a workaround, I have another TextBox in cphMain with the SqlDataSource which has Visible=False. Then in the Page_Load() event handler the contents of the TextBox in cphSideBar is copied into the contents of the non-visible TextBox in cphMain.

I am having a problem with using A Gridview SectedIndex or value in a sql ControlParameter. When I select the row it does what I need it to except it shows that there is no data.
but if I add Default Value of 1 the data shows up, but it needs to read from the Gridview.
[Code]....
I even added sqlDataSource.DataBind() in the SelectedIndexChanged Event to see if that would fix it but - No! I used it with a DropDown and it worked only when I use AutoPostBack = true of course.

I have a gridview tied to a sqlDataSource. I want to filter it using FilterExpression of SqlDataSource. The controlParameter that I want to use is dropdownList SelectedItem.Value. This value is an integer. I am getting this exception: System.Data.EvaluateException:{"Cannot perform '=' operation on System.Int32 and System.String."}

I have an ObjectDataSource with a number of parameters. These parameters are binded in my FormView EditItemTemplate and the ItemTemplate. My Stored Procedure column names in my ItemTemplate are different to the Bind properties used in the EditItemTemplate. This is obviously throwing an exception when I update a record.
Instead of using Bind("Columne Name") in my EditItemTemplate how do I use a ControlParameter to reference a TextBox in the EditItemTemplate?
I may be wrong but I'm trying to use the PropertyName=Controls but i do not know how to reference the Textbox in the EditItemTemplate.

I have following in many controls:
<asp:ControlParameter Name="SvcCluster_Id" ControlID="frmConfigEdit$ddlCluster" PropertyName="SelectedValue" />
Everything was good before I bumped into the problem when declarative binding (SelectedValue='<# Bind("SvcCluster_Id") >') produced the error, because value has not been found in the list. So i moved binding to the code:
protected void frmConfigEdit_DataBound(Object sender, System.EventArgs e)
{
if (frmConfigEdit.CurrentMode == FormViewMode.Edit)
{
var svcCluster_id = DataBinder.Eval(frmConfigEdit.DataItem, "SvcCluster_id");
var ddlCluster = (DropDownList)frmConfigEdit.FindControl("ddlCluster");
if (svcCluster_id != null && ddlCluster.Items.FindByValue(svcCluster_id.ToString()) != null)
{
ddlCluster.SelectedValue = svcCluster_id.ToString();
}
}
}
But now seems like this happens later than ObjectDataSource tries to access frmConfigEdit$ddlCluster...
How to manage this?
I wouldn't like to move everything to the code (I mean creating Control parameters, etc)
p.s. Oops, actually it works ok for DataBound event! Sorry.

I am trying to do a version of this post, but with the EntityDataSource. I think I am close, but it seems that the "InsertText" and "Insert" command in the code-behind do not carry over. Here is what I have so far, but please help me fix it. In addition, in the .edmx the Table "UserProfiles" inherits from "aspnet_Users"

I have a simple user control that I have placed inside a repeater. I want to access it through the ItemDataBound event of the repeater. Here's my code so far:
[Code]....
Not so sure what to do about all of this. I have developed a simple calendar using an XML doc and a repeater. The parent repeater contains a child repeater that lists events based on the date. I have a User Control that has some unique capablities for control the date in a link button. I want the user to click on the User Control and be able to use the information to do something. Bottom line, I want to access the linkbutton inside the repeater.
