Forms Data Controls :: How To Access A Newly Added Row In A Grid Using Objectdatasoure
Apr 26, 2010
I have a grid which uses an objectdatasource. Data is correctly retrieved using the select method. When I add a new record a new row appears in the grid and I can enter my data. I do have access to the row on saving as I can access this new row from the Grid's insert method - using the GridRowEventArg like so (this is using an Obout grid control but the principle can be seen):
protected void WeekTimeListGridView_InsertCommand(object sender, Obout.Grid.GridRecordEventArgs e)

I have a FileSystem based asp.net 2.0 app that uses Sql Server 2005 Express database.
I have only one dataset for this app with only 4 tables. After i have completed it to a part, a co-worker have added some Classes to it, which are not in same namespace of myBLL classes.
Then i tried added a new table to the dataset. It like all other tables in that dataset uses SQL Statements to access and manage data.
The problem started after i added that new table. I cannot access it from code. I can access all previous TableAdapters but not this new one.

Recently i am working in VS2008 installed in windows xp SP2. In the toolbox i added a new tab and added some third party controls in the toolbox, by using "Choose Item" dialog.. I also added Ajax ToolKit to the tool box. It worked fine and i could drag n drop controls.
But then if i restart VS2008, all the tabs i created and controls in it goes off and disappears ncluding Ajax Toolkit. Each time i restart it, I have to have add those controls newly?
Is this a Bug?? or Is there any solution for this?

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);
}

I am working on a web form using VS 2010. The controls I've added previously to this form will show in the drop down list in code behind and are available to add events too. However any new controls I've added for last week or so are not visible in the list. I cannot access their events. I have scoured the forums and tried everything I can think of, nothing works.

I 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 been trying how to make a dynamic controls in ASP.Net and figured out that it was the same on VB.Net like this.
Code:
Dim objCheck As New Checkbox
With objCheck
.Name = ""
The only difference is that instead of "Name" that should be "ID" and "Location" should be "Attribute("style") = "top:100px; left:100px".
Now I'm getting this error saying that "it should be place in a form tag and runat="server"".
BTW, that adding of dynamic controls is place in Page_Load()
Secondly how to add an AddHandler of that newly added control ?

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 working on Crystal Reports 8.5 and SQL Server 2000 as backend. I have a stored procedure which has been added to the Crystal Report. So that fields are visible in the Fields object section from where i can drag and drop the fields on the report and display it. But now as they want more fields i have written two select statements for displaying required fields. But these newly added fields are not visible in the Fields object section in the Crystal Reports. I have done verify database, removed and again attached the SP but the problem is not solved.

I have search for a long long time and could not find a solution to access to grid view's column properties. I have binded a grid view through this method, the bindGridView function will return a table with columns and rows.
The problem here is I cound not access to columns properties such as Grid_View.Columns.Count or Grid_View.Columns[0]."something". It seems like the grid_view does not have any column. But I can access to the Rows properties.
I have put this code within a (!IsPostBack) and set the AutoGenerateColumns to true?
I need to access to columns badly as I need t add additional column to the binded grid view.

I thought this would be easy before I started, but I should've known better.
I just need to get the value of primarykey from the newly inserted record so I can pass it in the query string to the next page the user will be directed to.
Here's my code:

I had found what looked like a good soultion yesterday by the moderator "ecbruck" at this post:
[URL], but after spending many hours trying to figure out why I couldn't get it translated and working in my own project, I found that MS Access does not allow use of an Output Paramter. And unfortunately I don't have time to teach myself a new database platfrom and am stuck with MS Access for the moment...teaching myself asp.net has my head spining enough as it is.

I've got a FormView control on a page. Its default mode is insert, since the intent is to have the user enter a record, save it, and then do something else. I've written a stored procedure to insert all of the data into 5 tables. 1 of the columns inserted is default, in SQL Server 2005, as an INT column, which is an IDENTITY column. After it inserts the record into the primary table, using a secondary stored procedure, it retrieves the newly created INT value, and then the primary stored procedure inserts records, using the new INT, into the other 4 tables. This is working fine. The primary stored procedure, which is called by the SqlDataSource on my .aspx page, defines this parameter as an output parameter:
[Code]....
In the FormView's ItemInserted event I'm trying to get the value from the FormViewInsertedEventArgs e parameter like this: [Code]....
However, the result returned is 0. Huh? That cannot be, because the new INT value created is something like 145000. Why am I then seeing a value of 0?

after a DetailsView (DV) 'Insert' (triggered by a DropDownList (DDL)) the DV shows the first record (in the DDL)!Are there VS2008 means to keep / show the just entered data - again ready with the command row "Edit/Delete/New" enabling me to e.g. "Edit" the just entered data?This DDL/DV scenario works just fine but to show my just entered record I have to leave this page and start calling this .aspx page again in order to see the name in the DDL and, hence, in the DV.I.e. I'm looking for a kind of automatic 'postback' bringing my just entered data back
