I have a DetailsView being populated from a database.
I'd like the header text for the fields to be be bound from information gathered from the database. Is this possible?
E.g.
[Code]....
in my application the gridview header is dynamically binded in RowEditing,RowUpdating and RowDeleting events.when i am deleting any row from gridview it will show an alert boxwith a message
Are you sure to delete?
the code as follows[Code]....
when i run the application the header is binded in RowEditing,RowUpdatingevents.but it is not binding in RowDeleting Event.
i have a gridview bound to sql datasource with template fields binding the columns. I have set the Header Style to a css class. I have 3 columns not bound to data as Add, Edit and Delete. When I set the text color to white for the header only the non bound columns go white. The bound columns are BLUE like hyperlink. Any one know a way round this. (If I set the style in the gridview the all columns are white. Want to set in external css file).
[Code]....
I'm trying to bind both GridView and DetailsView to a single ObjectDataSource declaratively (in markup). I'm getting the error read as below when I tried to run it.
"The DataSourceID of 'DetailsView1' must be the ID of a control of type IDataSource. A control with ID 'ReservationsDataSource' could not be found."
It works when I bind GridView and DetailsView each seperately to my ObjectDataSource. Is it I can't bind two pagable data web controls to a single datasource?? or there is a trick needed to be done for this to work.
FYI, I'm trying to create a Master/DetailsView of my data. DetailsView of my application should show the record selected in GridView and it should be editable.
How do I bind a DropDownList inside a DeatilsView?
I have something like that... but I'm unable to bind it.
[Code]....
I am currently binding my Detailsview and Gridview together by a "ID" field selectedvalue "1". Which works great except for the fact that I don't want the user to have to go down to the gridview and select the page and then the record to view it in the detailsview.
I have 1 sqldatasource for detailsview and another sqldatasoure for the gridview. Both have the exact same select statement.
I want the gridview and detailsview to automatically display the last record inserted not the first record in the table.
I have a bound field in a DetailsView that I want updated with the contents of TextBox2.Text when I update. I have TextBox2 set AutoPostBack True. Cannot remember how to move the contents on update. I tried converting the "Description_Update" to a template field without success.
I can copy and paste the contents of TextBox2 into the DetailsView and it does update as do the other DataFields.
<asp:TextBox
ID="TextBox2"
runat="server"
Height="80px"
TextMode="MultiLine" Width="360px"
Font-Size="Small"
MaxLength="120"
Text=""
Font-Names="Calibri" AutoPostBack="True"></asp:TextBox>
<asp:BoundField
DataField="Description_Update"
HeaderText="Descrip"
SortExpression="Description_Update"
/>
Do I need to use adn Eval or DataBind function or both. I have triued several combinations and do nothing but continue to butcher the database tables.
I have a details view in asp.net which I am dynamically replacing some of the controls using code behind (e.g. converting some text boxes to dropdowns). My problem is that I am unsure how to bind these to the field from the database on postback. I.e. I am trying to find the code behind equivalent bind('currency');
I can populate the dropdown with the current value from the database but cannot find how to save a new value on updating the detailsview.
I want to dynamically bind dataset values into datagrid's header datafield.
Is it possible? To be more clear, when you click on datagrid's (Collection) from properties window, you get selected columns created from Bound column. So in those columns I want to dynamically display dataset's table values in those columns.
i.e like ds.Tables[0].Rows[0][0].
Is it possible to do it in Datagrid ItemDataBound function like,
e.Item.Cells[1].Text = ds.Tables[0].Rows[0][0]
or something like this? I know the above code is wrong and wont work since I tried it out and while building it throwed error saying, Cannot implicitly convert type 'object' to 'string'.
I have a DetailsView (DV) control, an ObjectDataSource (ODS) control, and a button on a page. I have 2 classes in the App_Code directory (Customer and CustomerDAO). The DAO class provides static methods for the ODS control and simply hack values in (ie...no real database selects/updates). The Customer class has 2 properties (Id and Name) and a default constructor. The page takes an ID on the querystring and determines if the DV control is in insert or edit mode. If in edit mode, it sets the SelectParameter on the ODS (id field), calls ODS.Select(), and then calls DV.DataBind(). The existing (although fake) customer is loaded and display properly when this happens. I then change the name of the Customer in the DV and click the Button to save the new data.
Everything seems to be wired up correctly as the UpdateMethod that is specified in the ODS control is called and succeeds (even in my real example with my database). The problem is that the BoundFields in the DV control have not been updated with the new values and therefore the existing values are updated in the database and my changes are lost. I have handled the OnUpdating event of the ODS and the values are still the old values. I have also handled the OnItemUpdating event of the DV control and the NewValues IOrderedDictionary still has the old values in it also. In looking at the MSDN article for the UpdateMethod, it states the following:
Parameter Merging
Parameters are added to the UpdateParameters collection from three sources:
From the data-bound control, at run time.
From the UpdateParameters element, declaratively.
From the Updating event handler, programmatically.
I am using the BoundField classes in my DV control so I would have assumed that the first bullet above would have handled the updating of values, but it doesn't appear to work with the way I am doing it. If I set the values explicitly in the OnUpdating event that is fired by the ODS control (the 3rd bullet) the right values are updated (again...even in my real database situation). It seems like my only issue is that the automatic binding that I expect from the DV control isn't working as I would expect it to. Here is the code that I have in my fake example:

is it possible to bind the value in header control of gridview .

I display the incrementing number in the header. I create a column to show the current Row Number, but I'm not sure how to display the header text (Incrementing number) in the corresponding footer. Is there a special trick for it if I'm creating columns on the fly?
Is there any way to get the datagrid header column's text before the grid loads.
View 7 RepliesI want to fill a gridview with data from a database table..But, I have to avoid the column names from the database..I had already specified header text for the gridview.. i had already selected two column names 'name' and 'number' from a database table, then I had created two columns for the gridview( with header text's name and number)..Now i want to select the all the data from columns 'name' and 'number'..and then fill the respective columns.
View 11 RepliesI have a gridview which is binded to a table at runtime.So when the gridview displays the header text is exactly same as table field text which I want to change ,How can I accomplish thisFor example my table field name is MembershipNumber, so my gridview header also displays the same name. What I want is I want to change the header text to Mem No instead of MembershipNumber
View 5 RepliesI am wondering what is the best way to do this. Here is my observation:
1. If a GridView is assigned a datasource at design time, the header row's text can be retrieved with ((DataControlField)GridView.Columns[index]).HeaderText.
2. If a GridView is assigned a datasource at run time by code-behind, the header row's text can be retrieved with GridView.HeaderRow.Cells[index].Text.
Is there a way to do it without trying one, if not working, then the other of the aforementioned methods.
I have a simple GridView in my page which it bound to Database using Connection String in vb.net.(I am not using SqlDataSouce of Asp.Net)
When it bound to db, I can not change the header text of columns.
Here is the code behind:

I have even used the GridView1.Columns(0).HeaderText = "some text"
I have a gridview of months and numbers where months are 1-12 i want the months to be Jan-Dec and im doing a check like this to change them
[Code]....
But the problem is , its also checking the data and if it find 1-12 it will change it to a month like this.

I have a GridView (inside an update panel) that has header text that changes based on some user profile information. I set the header text in the Page_Load function of the page - that works fine. The problem is that when I change to the page number of the GridView, the header text is not redrawn. I am handling the OnPageChanging event to try to update the header text but nothing is happening. I've attached the relevant code.

I have my data table generated dynamically binded to grid view. (Autogeneratecolumns true)
in my UI its displaying the column headers.
am not able to access it by grdname.HeaderRow.Cells[0].Text
am not able to get the names from the columns also.
since am binding the columns dynamically i am not able to get access to all the columns
and am able to get only 2 columns which i have mentioned in my aspx which are the command buttons edit and delete.
am trying to access all these in Gridview_RowCommand event. need to get the value in the (dynamic) column named Id for the row on which the edit or delete button is clicked. since it doesnt have a header am unable to access it bcoz i dont know the index of the cell too..
i hv a grid view with coloum chambrno and floor1,floor2 upto floor 9.i hv taken a select button on all these coloum except chmbrno.now on select button i hv bind the data from the tables.hw can i get the name of the coloumn of the select button clicked.is it possible to get the column name of header text of the clickd select button
View 1 RepliesI guess I'm not sure exactly how or where to do what I need.
First off - here's what I need - - when the user clicks on the NEW button in the detailsView, I have the User.Identity.name captured in a variable and I need to set one of the textboxes (InsertItemTemplate) named 'txtNew' to that name.
I've tried using the ModeChanging (and ModeChanged) event:
Dim
dv As
TextBox =
CType(DetailsView1.FindControl("txtNew"),
TextBox)
If (e.NewMode =
DetailsViewMode.Insert)
Then ....
However, no matter what, 'dv' always shows as 'Nothing', so I can't change the text of it.
Where do I put the logic and what am I missing?
I am trying to programmatically set some lables inside a DetailsView that is populated by an ObjectDataSource. The detailsview is handled in an unusual way with one TemplateField that has one ItemTemplate that has one table that has two rows of significance and a boatload of bound items. I'll be working on the EditTemplate next. But now I need to set the top row lable values programmatically baised on the type of data that comes-up. I have scoured the Internet looking for ideas and found two possible approaches - neither worked. I get the error about something not being set to an instance of the object - or something like that.
Here is the ObjectDataSource:

Here is the DetailsView:

My first approach was to set the OnSelected property to the following code in the code behind, which executes:

My second approach was to delete that OnSelected property and try the following code in the code behind:
