Forms Data Controls :: Bound Textbox Not Populating In Gridview?
May 25, 2010
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?
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?

1. textbox (Search for staff) 2. Dropdownlist( Search for department) 3. Listbox( Populate staff name based on textbox or dropdownlist)
I am able to populate the staffs indenpendantly according to what is written in textbox or dropdownlist. Whar i wanted to do is mix the population of staffnames from textbox and dropdownlist. In other words, when i search "sandra' in textbox and select a Department A , the listbox will show all the sandra from Department A only.
I have a TextBox in a nested FormView that I want to use for entering a date. I have added a calender extender to the TextBox and I want to set TextBox to read only so that the date can only be entered by using the calender extender. This way I can avoid improper date formats.
The problem is that when I enter a new date and click the Update button, the new date is not saved to the database. I have done some searching on the WEB for a solution, and I found that "Page.Form.SubmitDisabledControls = True" is used in the Page_Load event to solve this problem. I have tried this and it does not work.
Another solution that I have seen is to set the control to readonly at runtime in the FormView "ItemCreated" event. I have been unable to access the "ItemCreated" for this FormView because it is nested.
i am poupulating data from database which was saved using Rich textbox in vs2003 into a text box in Vs2005.But,i had problems when the data is populated.I am seeing some ascii characters as textbox doesn't know how to present formatted data.
I'm not sure how to search for what I'm seeking, so I'm hoping to be pointed in the right direction.
I have 4 gridviews that contain the same 3 rows of data. For each gridview, I need to create a seperate gridview that will do some calculated values on the parent gridview like A3-A1, to put it in spreadsheet terms.
And at the very bottom I will have a total gridview control that will sum up each row from the parent gridviews. And under that gridview a final gridview to perform the A3-A1 calculation.
If the gridview binds to empty dataset, I need to still show a gridview so that users can ADD more using the textfields in the bottom of the footer template. Since the gridview is empty it won't bind not allowing rendering of the <footer template> I guess I should create a empty dataset if the gridview is empty. How do I check for this and can this be done in GridviewRowEventArgs
Protected Sub gvPunches_RowEditing(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewEditEventArgs) Handles gvPunches.RowEditing Dim i As Integer = e.NewEditIndex() Dim ddl As DropDownList = CType(gvPunches.Rows(i).FindControl("ddlDiv"), DropDownList)
the question I have is when i enter this procedure in the code behind, ddl is nothing. what am I doing wrong in populating the dropdown for the row I am editing?
I am developing an application using Sharepoint Designer.I need to retrieve data from a database for display on the screen.The way I am hoping to implement this is to have a Text box from which data is taken and at the click of a button passed to the procedure (which is within script tags) which calls a stored procedure passing it the value entered in the text box.The problem I've having is that the gridview is not displaying anything (i.e. other than text i entered in the EmptyText property of the gridview ("There are no records"). Below is my code

I have a foreign key (TeamID) in a GridView. I use a TemplateField to display it as the lookup value (TeamName) in a label, and a dropdown for editing. When row is selected and SelectedIndexChanged is fired, I want to access the TeamID. 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?
during edit mode i populate the drop down in question with data based on a value selected in another drop down also in the gridview, all works find, but the paramater is not being updated with the selected value, i think this is because i do not call any Bind in the aspx side.
I have a form that has a textbox, a button and a datagridview. The textbox is a parameter of @subschedule. I'm needing to pass the value of the text box to my sql stored procedure and then fill my datagridview with the results of that query.
I have a gridview that is populating from a SQL DB and working fine. However, based upon certain data I find in fields in the SQL table, I want to place a 'n' or a 'y' in extra columns in the gridview that I am assuming need to be templatefields. My thought was I could maybe add 8 template columns and then I could put a 'y' in the appropriate column based upon the data I find the table. For the life of me, I cannot figure out how to do this. I want to do this at rowdatabound time ( i think) but I just cannot find out how to, in my code, put that 'y' in the columns. Is this the right way to do this or do I need to do it another way? How do I get that 'y' in the proper column?
I have a ListView (in an update panel) bound to an ObjectDataSource (connected to an NHibernate object) and in the EditItemTemplate I use Text='<%# Bind("HideLocation")%>' to bind to a string property of the object.
When I click edit (twice, another issue I'm having) and view the code in Chrome, the output looks like this:
why the value of the bound data (in this case: In locker 2317) is showing up outside of the text box instead of as the contents of the data?
I am having a hard time updating from my gridview based the value that I am setting in the datakeynames it is the Ucc field I keep getting and index out of range exception on the e.keys. I have done this before so I am confused what I am missing here.
what it is i have a datagrid bound to a datatable.This datatable fills from a sql table. This datatable will have 2 columns which is 'part' and 'description'.What it is I want to have a couple of chk boxes next to the datagrid which will filter it by column 'part'.The issue is the datagrid will have about 1000 records so i dont want to do a for next loop searching for field part for a certain filter
