In my table I have 3 fields:
[inFrmDate] (this is the key field), [inFrmData], [totFrmData] (this accepts nulls)When I try to add [inFrmDate], [inFrmData] to the GridView I get the messageto the effect that the:
@inFrmDate scalar is not declared.
But as you can see from below it is declared:
<asp:SqlDataSource

I am working on a Webbased project, where we have a Master page with some child page. In the child page there is GridView control, Footer of this Gridview control have some TextBox control to get the input value from user and insert into database. Once the data is inserted into database. We are reloading the inserted data into the same Gridview control, But Gridview control is hot Binding/showing up the recently added record.
I debugged the code and seen the Dataset which is getting the data fron database have the updated row but after binding to Gridview control. The Gridview control not refreshing the data. This is happening while we have Master page and child page.

I have a nested gridview dynamically added. It seems I resolved all issues with the loading this control on a parent page along with other controls and I can trigger the edit of the first level - the master part of the gridview. However, I cannot trigger the edit on a child gridview.
OnRowEditing="grdChildGridEdit_RowEditing"
The master and the child gridviews have objectdatasources in a markup but I have to do the additional data binding after the loading the control on the parent page (see the code below). I'm doing that additional data binding only for the master gridview that is working fine and shows the data for the master and the child gridviews. When I click the Edit button on the master gridview it shows text boxes for the editing but when I click the Edit button on the child gridview it's doing nothing and moreover the editing mode for the master gridview is going back to the initial stage (labels).
I was trying to trigger it throughuse the registering the event:

I am programatically adding a control to an aspx page and binding a server side event to an index changed event inside the control. (It's a RadListBox from Telerik's ASP.NET controls) The problem is that on the postback triggered from the control, the event doesn't hit its eventhandler because on the postback the control isn't defined. Is there a way to handle this without having to retrace the logic taken before and rebuild the controls so the events that stem from it are processed?
View 1 RepliesI've looked all over for a solution to my problem and i haven't come across a solution that works for me, at least i can't figure out how to make them work for me.I am creating a group of rating controls and adding them to a placeholder. I want to retrieve all ratings and update my database after a button clickall worked wonderfully, i thought i was making some real progress but then i noticed i could not get the value on the server side no matter what i tried... i noticed it's overwriting the value on a postback(i am assuming) i tried adding a if not isPostback statement but then it threw a callback error. anyway here is some code:
Sub Page_Load(sender as object, e as eventArgs) Handles Me.Load
For Each DataRow As Row In DataTable
Dim r As New AjaxControltoolkit.Rating
r.MaxRating = "5"
r.CurrentValue = "0"

I have a Gridview on my aspx and i wonder if i can use validators like requiredfieldvalidator,comparevalidator or etc to validate a row is added or NOT?
View 4 RepliesI mean, it's easy to add a Button programmactically to an aspx page, but a server control's event handler probably has to be set early in the page life cycle (maybe before Control.Load event). As a result in reality, are dynamic controls rarely added to apsx pages?I wish there is a way to call postback at the server, so that a event is never too late.

View 1 Replieshow to place newly added or edited row at the top in the gridview
View 3 RepliesI have an image button in my gridview which I'm using to open a new window.
The code for my image button is:
[Code]....
This works fine, in that a new window is opened correctly, however, clicking the button causes a blank row to be added to the top of my grid.
I have a gridview in which I add extra rows manually (besides the regular bound rows).The manually added rows do not have a textbox, they are just text.The normal rows hold a textbox "minprice".Now when the user clicks the NewGarage button I want to loop through the gridview and get the values in each row for the minprice textbox.
Gridview structure looks like this:
MANUALLY_ADDED_ROW
NORMALROW <= enter value here works
MANUALLY_ADDED_ROW
NORMALROW[code]...
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 have a DetailsView using a LinqDataSource. I have it connected to DropDown so the user can select a record to edit. This configuration works. However when I add a record after I enter the data and press insert link the DetailsView reverts to another record. How can I make the DetailsView stay on the newly added record?
My add button calls:
protected void btnAddRec_Click(object sender, EventArgs e)
{
DetailsView1.ChangeMode(DetailsViewMode.Insert);
}
Using vb.net/asp.net 2005.I have an inner gridview.The outer gridview is "Authors" and in the inner gridview (GridView1 below) I have to set it up so that the user cannot delete the last book from the inner grid, if they try to delete the last book from that inner grid then I want to show the exception message below.
So I am checking the GridViewRows1.Rows.Count which works great when I have one record (one book) to start with. The problem is when I have 2 books (for example). I am writing out the test statement below and the RowCount is always 2 each time, never decremented, even after I rebind.Editing this now: i realize that my initial logic is faulty because when I rebind my inner gridview I am not specifying which inner gridview so the result is that only the last inner gridview is being re-bound, so I think that I need to get the selected inner gridview and then refresh that...

I have a SQL table containing a timestamp column. This table is displayed in ASP using GridView control. The timestamp column is indicated in the DataKeyNames property of the GridView. I'm using TemplateFields for all columns and a ItemTemplate HiddenField control connected to the timestamp column using Eval.
<asp:TemplateField
ItemStyle-Wrap="false"
Visible="false"
HeaderText="timestamp"
SortExpression="timestamp">
<ItemTemplate>
<asp:HiddenField
ID="gv_hid_timestamp"
runat="server"
Value='<%#
Eval("timestamp") %>'
></asp:HiddenField>
</ItemTemplate>
</asp:TemplateField>
The data is displayed properly. I'm trying implement the optimistic concurrency in C# using the value of above mentioned timestamp and a stored procedure. The SQL stored procedure expects the @timestamp as varbinary(8). I'm not sure how to pass the value of gv_hid_timestamp back to the stored procedure. I'm using the following:
command.Parameters.Add("@timestamp", SqlDbType.Binary).Value = Byte.Parse(((HiddenField)gv.Rows[row].FindControl("gv_hid_timestamp")).Value);
resulting in the following error: "Input string was not in correct format." (I also tried different data types but with similar result). I want to be able to pass this parameter programmatically from C# and not have to specify it on the UpdateParameters list.
All of my columns are bound in the Gridview. On OnRowDataBound event, I am adding some custom styles like underlines and colors to the text of the columns. Sorting of data is working fine but I am losing my custom styles when I sort. I am using the generic sorting code for the GridView.
How I can keep my custom styles on sorting that I added during OnRowDataBound event.
I have problems building a GridView programmatically. My code is:
[Code]....
This displays the GridView with the following problems:
1. The Html constructed in the Subject column displays on the page as raw Html. The source code shows the Html characters in their ASCII form. The function HTMLEncodeSpecialCharacters is obviously incorrect.
2. The PagerSettings display the page numbers only (1 2 3 4) and not the First and Last text (want to display << 1 2 3 4 >>) despite setting PagerSettings.Mode = PagerButtons.NumericFirstLast.
3. Clicking the page numbers is always one page behind. For example, when the page is opened, page 1 displays. If I click 2, page 1 still displays. Then click 3, page 2 now displays. Click page 4, 3 displays. Click 2, 4 displays etc etc.
4. The column headings are aligned in the centre despite setting HeaderStyle.HorizontalAlign = HorizontalAlign.Left.
