Forms Data Controls :: Getting Error / Could Not Find Control 'GridView1' In ControlParameter 'ID'
Jul 2, 2010
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.
The error I get is:
Could not find control 'GridView1' in ControlParameter 'ID'.
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.
Exception Details: System.InvalidOperationException: Could not find control 'GridView1' in ControlParameter 'ID'.
i'm using Relational Tables and during Edit, my Drop Down list is a lookup column from the Master table, but when i try to edit it works and shows the records the only problem is that when i udpate, i get the error (Can't find control DDLSongs (my drop down control) in @AlbumID Parameter) below is the code for ref.
i have two tables (Albums,Photos).befor i want insert a record in a Photo table i must select name of album so i create a user control that have a dropdownlist and a datasource(Albums table) until when i select a name of album put AlbumID in a Property(SelectedValue) when i use this user control in details view in edittemplate i have an error
--->error could not find control 'SelectedAlbum' in ControlParameter 'AlbumID' my code id:
public partial class Admin_SelectedAlbum : System.Web.UI.UserControl { public string [COLOR="Red"]SelectedValue[/COLOR] { get { return DropDownList1.SelectedValue; } } protected void Page_Load(object sender, EventArgs e) {.........

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'.

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 can't figure out what I"m doing wrong.. I followed this sample online at http://www.4guysfromrolla.com/articles/091102-1.aspx to include a gridview in an email. But, it keeps throwing this error.. 'GridView' must be placed inside a form tag with runat=server.I've verified that the gridview is in a form, and there are no template fields in the gridview. Heres the gridview on my asp.net page..
I have a webpage with a select object and a GridView object. For testing my problem i've created asp button and html button.On pageLoad the GV is empty and select is being filled with names. (GV is not appearing)After choosing a name from the select options, the user should click a button and then the GV need to be filled with relevant info.I am having 2 "related" problems:
1. When clicking on the asp button and getting into the click function on the aspx.cs file, i can't find the select object and retrieve the selected option. How can i get this?
2. When clicking on the html button and getting into the button_click function on the aspx file (javascript), i can't find the GV object (getElementByID("GridView1") returns null). I guess that it's because the GV is not loaded initialy since it's empty.I've tried also using callback methods, but the although it seems like i am reaching the GV and performing DataBind(), the GV table won't show on the page.
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.
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 started a C# web project in Visual Web Developer. I dropped a grid view in with designer and connected to my remote SQL database with the designer dialog based wizard. All is well there. I have in my program also a textbox where a user enters a zip code and clicks a button 'search'. When the user clicks search I want to run the SQL command "select * from flat_list where zipcode='userszipcode'". In other words the userszipcode is dynamic and different every time. It is my understanding I should use a SQLDataSource object but I do not know how.
i have a gridview control i added checkbox contrl dynamically but i am not getiing the reference of checkbox in button clilck event here is my code Gridvew
I have a gridview1 with a Select column, which has a SqlDataSource that executes a Store Procedure.
I also have another gridview2, which also has its own SqlDataSource, but in this case, the Store Procedure has a parameter. This DataSource assigns as parameter the gridview1 control, and its PropertyName is SelectedValue. How can I load the gridview2 when gridview1 is clicked in the Select Column?
I have a dropdownlist (ddlList) in gridview1. I need to reference that ddlList as my ControlID for the parameter.
I tried to define gridview1.ddlList, but this did not work. Is there any way (non-codebehind) that I can use to reference a dropdownlist which resides in gridview1 from gridview2?
I have a default.aspx page which has two gridview controls i.e. Gridview1 [Displaying Order table] and Gridview2 [displaying OrderDetails table], when I am deleting a row in GridView1, GridView2 should also update its datasource because of referential integrity constraints.
Following is what I am trying to do in GridView2_Load event:
I am Just Filling My GridView using OleDb Control from Excel Sheet. and When I want to Save that I must have to Go through the Number of Columns to read at the End of Record.
I am Using
Dim Rows As Integer = GridView1.Rows.Count Dim column As Integer= GridView1.Columns.Count msgbox(Column) '--> Here I am Getting Value Zero for i=0 to Rows-1 Fori=0 to Column-1 'Work to Perform Next Next
I am using ASPNET2008 with VB Scripting and not C# Scripting I am encountering new problem.
On the WebFrm1, I just don't know how to write the coding to retrieve the CUSTOMERID data in order to retrieve the details from SQL SERVER table to fill the textbox controls.Here is the decription of the GRIDVIEW column
In the GRIDVIEW1 on the left edge one of the column is SELECT button which let the userclick on it to select the specific CUSTOMERID on the column next to it on the right.
I have a gridview code behind like below, and in the aspx page I called it <%# Eval("TrackedUsername") %> which displays a cell for me that has the username. Now, in my code behind, I want to be able to retrieve that data (username) from that gridview1, how can I do that?
I have 2 Gridviews of the same structure and header. I want when user click hear of Gridview 1 for sorting, the same sorting applies to Gridview2 onclick.
