Forms Data Controls :: Get ID Bound To Label In GridView?
I have aforeign key (TeamID)in a GridView. I use a TemplateField to display itas the lookup value (TeamName)in a label, and a dropdown for editing. When row is selected and SelectedIndexChanged is fired, I want to access theTeamID. I can get the TeamName from the label. I tried putting the TeamID in DataKeyNames, but that fouled up my dropdown when saving (it reverts to the original value). So, how can I get the TeamID?

Forms Data Controls :: Custom Sorting Bound GridView
I have a GridView that is bound to a MSSQL table.I need to sort it based ona column; however,I need to implement a custom comparisonto be used for sorting.It is avarchar column with entries such as (1, 2... 300... 1000... 504-2). I have a comparison in place that I use in other applications to sort the versioning strings; however I can't seem to find a way to use it with the GridView.If I use the built-in sorting, I get the typical problem of 1000's being tossed in with 100's and such.

Forms Data Controls :: Gridview (bound By ObjectDataSource) Sorting
I have a gridview being data bound by an objectdatasource which points to a BLL/DAL.I have paging and sorting enabled within the gridview. I have the fields configured in the look/fell I want from a templatefield.This templatefield has the sort expression (date) I want things to be sorted by. All this works as it should and I have no issues with it.But, the issue is that when I click on the header to sort asc/desc by date, I have to click on it twice for it switch to descending order.E.g.I hit the webpage and it lists all the information in the gridview, sorted by date, ascending order.If I want to sort by descending order, I have to click the date header twice in order for the gridview to sort the information in descending order; the clicks cause a post-back and the whole screen is refreshed.

Forms Data Controls :: Applying CSS To GridView During Item Bound?
I am working on a ASP.NET 3.5 application. I am applying the CSS style to GridView control in the Item bound event of the Repeater control.Following lines of code will be executed10 to 20 timesduring the Item bound event of the Repeater control.

grdSummary.DataSource = dt;
tblGroupHeader.CssClass = Class.Text;
grdSummary.CssClass = Class.Text;
grdSummary.HeaderStyle.CssClass = sumTrTitle;
grdSummary.ItemStyle.CssClass = eRowClass;
grdSummary.AlternatingItemStyle.CssClass = oRowClass;
grdSummary.DataBind();

Some of the CSS class has image url property and background-image:url(../img/r_header.gif);The page takes more time to load after applying the styles. When i remove the styles from the Item bound event the page loads faster.SoWhat is the efficient way toapply the CSS styles to Gridview inside a repeater control?

Forms Data Controls :: Bound Textbox Not Populating In Gridview?
I have a Gridview that has a template field containing a bound textbox (fieldname is 'Status'). I have an extra column containing an update button, which is designed to update the db with whatever is in the textbox.

What's happening is that when I load the form, the textbox is blank, even though there is existing data in the fields. If however I click the update button, all the textboxes in the Status column update and populate with the correct data from the database.I guess my question is why would bound textboxes not populate until an update command is run?

Forms Data Controls :: GridView Bound To ObjectDataSource Not Populating
VS2010 Ultimate ASP.NET 4.0 Web Appliction project

I have a simple aspx page with a GridView Bound to an ObjectDataSource utilizing a class object that returns a DataView.

There are no errors generated, but the GridView does not display any rows. If I check the return value of the ObjectDataSource in the Selected event in the Immediate window (?CType(e.ReturnValue,DataView).Count), there are 51 rows. However, (?Me.GridView1.Rows.Count) shows 0 rows. The exact same page in VS2008, ASP.NET 3.5 works fine. how to get the GridView to display the rows? What has been done to the GridView in 4.0?

Page and code below -

Forms Data Controls :: Formatting Bound Data In Gridview Using Client-side Javascript?
I am looking for a method to format gridview bound data using javascript.

I know you can have custom formating in Eval using:

[Code]....

But I am looking for a way to perform this task on client side, rather than doing it on the server.

For example if I want to format a date field being bound in a custom way, something like emails date received in gmail. (Only show time if it is today's date [15:30] and only show day and month if it is this year date [14 Jan] and show the full date if it is not this year [10/10/2009].

So, how I use javascript to format a field (ie. custom date format or setting a control visibility)?

Forms Data Controls :: GridView Bound To Data Table Object But Not Being Displayed On Screen
I have a GridView control that is assigned to a DataTable object. after being assigned to the GridView, the data in the data table displays as it shouldin my GridView on the screen.At times I will need to delete a row from the DataTable object.If I do, then I need to rebind my GridView control to my updated DataTable object. Everything looks good in the debugger, but when my GridView control displays on the screen, there is no data in the GridView control. Below is the source code I am referring to

DataTable dtCurrentTable = (DataTable)ViewState["CurrentTable"];
dtCurrentTable.Rows.RemoveAt(gvr.RowIndex);
dtCurrentTable.AcceptChanges();
Gridview1.DataSource = dtCurrentTable; // Yes, dtCurrentTable has data in it
Gridview1.DataBind(); //

Why won't it display on the screen?

Forms Data Controls :: Display Hyperlink In Gridview Bound From Datatable
I have a gridView which is populated with the code below. This is working perfectly except for one issue. In the "Region" column, I need for each region name to be a hyperlink. If I set the row code to dr(0) = "<a href='table_display.aspx?IO_ID=" & objDataReader("IO_ID") & "'>" & objDataReader("Region") & "</a>" it actually displays the entire string of text from "<a href..." through "</a>", but not as a hyperlink. I have read in many places to manually put a hyperlink field in the aspx page, but I would really prefer to do this programmatically in the code-behind.

Forms Data Controls :: Format Generic List Bound To Gridview
I have a generic list of a custom type. The custom type has a string and double.I'm binding the list to a gridview and it outputs everything fine.I'm trying to format the double column into a currency format. It is in a template field as I'm calculating a running total. I pass the value to a function that returns a double and adds the current value to a running total which I will show in the footer.

The format is not changing to currency as expected when using String.Format("{0:c}", GetTotal(Convert.ToDouble(Eval("Amount"))))

Forms Data Controls :: Format Inside Bound Column Of Gridview?
I have a bound column.

<asp:BoundField DataField="WorkPreference" HeaderText="WorkPreference"
HeaderStyle-HorizontalAlign="Left">
<HeaderStyle HorizontalAlign="Left" />
</asp:BoundField>
dr["WorkPreference"] = sa.WorkPreference ( This is how I bind the data to a DataRow)

The example of the data which gets bound to this column is like the following:

Communications and Marketing Officers; Environmental Assessors; Geologists and Geosciences; Geospatial/Spatial Information Officers;

What I want is that the data should be presented to the user like the following:

Communications and Marketing Officers
Environmental Assessors
Geologists and Geosciences
Geospatial/Spatial Information Officers

In short: I basicaly want to put a break where there is a colon and then bind the data to the gridview. It looks like simple but if you can let me know.

Forms Data Controls :: Two DataLists Bound To One GridView With Multiple DataKeyNames?
I have a gridView, with two DataKeyNames: MemberID, and CommitCustomerID.

One DataList has this sql statement:

SELECT * FROM [tblMemberProfile] WHERE MemberID = @MemberID

It pops up perfectly fine.

I also have another DataList with this statement:

SELECT * FROM [Incidents] WHERE CustomerID = @CommitCustomerID

I know this sql command works I have tested it with my data.

However I dont think the DataList is getting the proper value for the selected row in this DataLists case.

How can I make sure when I select the row in the GridView the proper parameters are going to the proper DataList sql statements?

Forms Data Controls :: OnRowCommand Not Firing If Gridview Not Bound On Postback?
I have a webpage with many updatepanels. Each panel contains databound controls including gridviews (GV). They are bound at runtime so the number of gridview columns varies with each bind. the controls are bound only once in Page_Load event ( within if (!Page.IsPostBack) )I added a linkbutton to each header in the GV in the RowDataBound event. Once the header is clicked, the event is handled in the OnRowCommand and it calls a method to bind the controls with new data.Things work fine if the GV is bound with every postback (no if (!Page.IsPostBack) condition) but I don't want to bind all the controls with every postbackMy problem is that the OnRowCommand is not fired if the GV is not bound on the postbackI even tried to add click handler for the linkbutton but that didn't work either.

Forms Data Controls :: Filter A Bound GridView With Radio Buttons?
I have a GridView control bound to an AccessDataSourcecontrol that has a default query assigned to the data control when the page first loads. I also have 3 radio buttons on the form that I would like touse as a filter on the data (i.e.change theWHERE clause in the query)in the AccessDataSource.

I am relatively new to this, so I tried the following:

I set the radio buttons to AutoPostback = True, and then putcode behindeach radio button's CheckedChanged event to change the query in the AccessDataSource:

MyAccessDataSource.SelectCommand = "SELECT ... WHERE <new where clause>"
MyDataGrid.DataBind()

The problem is that when the page refreshes, all thecolumn widths in the grid end up expanded andthe grid is then re-displayed with its right edge well beyond the right side of the form. I'm not sure why the columns widths don't stay as they were originally since I am not changing them. Even worse, when one of the column headings is selected (I want column sorting), the page sorts the column and displays the grid based on the original query listed in the markupinstead of the most recent query assigned by the SelectCommand in the code behind.

The grid is bound to a dataset. Now when in view mode (ItemTemplate) the label displays the time correctly but when I click edit it displays the mask instead of the bound data.

Its probally something small but is doing my nut in. (Note: I also have a mask on a date textbox and that works fine)

Forms Data Controls :: Have A Gridview In Aspx Page Bound To A Stored Procedure?
I have a gridview in aspx page bound to a stored procedure, and data is loaded from the database. I have 2 problems which I am banging my head against.1. Stored Proc has default values of NULL ( which is a DateTime db type) and I don't get how to give them as default values and once I have valid date time ( from textbox on form) , I need stored proc to take this value . ( I have done this from server side code but if this is able to acheive from client side that would be great.

2. As shown below my gird view is present ( no columns are bound and since the data is loading from server side ) I am unable to do sorting on the gridview without a sort expression. Does any one know how to do this?? This is my biggest concern. I have checekd all the articles I could find on google

Forms Data Controls :: Insidious Bug Found For A Bound Gridview With UPDATE Command?
Bug: UPDATE command Does NOT Work as Expected on a DataBound GridView This was tested in VS2005 and VS2008

Took a while to figure this out - A simple recurse thru Page Controls Makes UPDATE Not Work as expected.

To Recreate this bug:

Asimple Gridview bound to anObjectdatasource on a page with ALLOWEDIT ALLOWDELETE

If one inserts some code (a function call in my example) that just recurses the PAGE controls in eitherthe PAGE_PREINIT, PAGE_INIT, PAGE_INITCOMPLETE events,

Then the UPDATE does not FIRE!and After Pressing UPDATEtheGRID does notBIND! You Get A Blank Page- Funny thing tought it's only the UPDATE Functionality that gets affected by this- Everything else works fine including EDIT & DELETE.

If the same function call (recurse thru page controls) is added in the PAGE_PRELOAD, PAGE_LOAD -- Then the UPDATE starts working again as expected.

BELOW Is SAMPLE Code using the NORTHWIND DB Products Tableand a Typed DATASET.XSD - You can use your own datasource for the ObjectDatasource - (Note I took outthe Foreingkey constraint in products tablefrom Nortwind for delete to work)

NOTE: One should be able tojust cut and paste the function PAGECONTROLS_RECURSETEST on any working form that hasa bound Gridview with Update functionalityand you should be able recreate the bug that way by calling the function from the different page_events

[Code]....
