Forms Data Controls :: Unbound Dropdown Box In Gridview?
Jul 9, 2010
I am populating a DataTable and binding it to a GridView's source.
I have a dropdown box in an itemtemplate in the gridview.
I want the dropdown to have 3 options and depending on what is in a column from row in datatable a specific value will be selected.
I was able to do this when I was binding gridview source by looping through SQL but now I that I am putting the results in a datatable I am not sure how to go about it.
This will create multiple fields in the gridview with some values. Say i have this field called "Sold" and it has the value "1234.5600" How can i display it like "1,234.56" ?
i use a gridview to show data from datasource, but i have some column in this gridview that they're not bound. If i go in edit mode, my unbound control show me the textbox to enter value and its ok, but if i modify value thru rowdatabound, now when i go in edit mode, the textbox are not showing as i expect, its just showing the value i put in rowdatabound, but i don't have the textbox to let me enter a new value and update it after.
And more in the same relation: with the two above condition i wrote, when i dont modify value in rowdatabound, i can modify value in prerender event with this line:
TextBox box1 = this.GridView1.Rows[this.GridView1.EditIndex].FindControl("TextBox1") as TextBox; box1.Text = "a value" ; but
when again i modify value in rowdatabound, the line above will not work too, box1 is load with a null value
I have a gridview control bound to a sqldatasource in c#. In the rowdatabound event I look at a value in a cell and use a function to evaluate the value and depending on that value I populate an added unbound column in my bound datagrid to show an excalmation point. I now want to sort by the column with the excalmation point.
i have a dropdown with month names if the user has data for the month tht is selected then gridview displays the rows with day nos as per the month but if the gridview has no data for the same the dropdown or gridview via some event should call a insert procedure to insert data into the table for tht month with daynos ad rebind the gridview witht the rows just created
I have a gridview where i have two fields. one is product and second is sub category.
I need to do 2 things.
1. I need to populate the two combos from the database. But depending what is selected in dropdown 1 this will determine what needs to be populated in drop down 2?
I have some template columns that have multiple textboxes in them.
There is one textbox for the Date portion of a datetime field and another textbox for the Time portion of the datetime field.
How do I populate those textboxes after the user clicks on the "Edit" button?
My assumption was I could get the data from the label that was displaying the datetime field data, break it down into Date and Time, and then access the textboxes.text property to fill those.
I can get the data from the label control, but when trying to fill the two textboxes with the data, I get Object Reference Not Set... errors.
Im assuming maybe those textboxes are not setup yet during the RowEditing Event?
I'm new to DataGridViews. I have successfully created an unbound DataGridView that contains columns of string, numeric and date values, but I can't seem to figure out how to define a column as a numeric or date value--only strings. I have enabled sort on the columns so the user can click on any column to sort by that column. When I click on the numeric column, it sorts like:
12345.56 13.35 1442.22 ...
The dates also sort as strings rather than dates.What is the code to change the data type of an unbound DataGridView column? Is it possible? If not, how can I do this with my unbound data?
I think it's very simple but i just don't see it at this point: I have a detailsview that's bound to a sqldatasource. I want to have access to the data in a field in the table thats not currenty bound/used in the detailsview. I have a table which has one collumn that contains a username of the user who submitted the record. This field is not bound in the detailsview.I want to have the detailsview show delete/edit buttons only if the current identity matches the value in this collumn of the currently bound record. But i don't want to show this field as a row in the detailsview. I thought maybe i can access this field in the databound event of the dview and create/show the buttons here. But how can a access this data if it's not used in a dview field? I also tried creating a templatefield for this field and set it to visible = false. But then i also can't access the data it seems.
The Datalist is being databound via an ObjectDataSource and everything here works fine. I have a label which I've added to my datalist and it's unbound to anything. Depending on the message information, I want this unbound label to display a certain phrase but it has to be next to a bound label. But if I try to change the text of the label in the code-behind, VS2k8 reports that the label is not declared. How do I do this?
I have a gridview with dropdown boxes. As soon as the complete gridview is databound, I want to loop through ALL the rows and set the values of the dropdown boxe in a row based on the value of another column in the same row. The gridview is databound, all data shows up. The condition "If ddl.Items(j).Value = searchstring Then" evaluates as true, but somehow the selected item in the dropdownbox is NOT changed and remains "<ignore>"
Is there a way to populate gridView in aspx page with some static Unbound data without making changes to the .vb file?I do not see any settings in the property window, checking to see if someone has the code?
The gridview will be populated with some columns with values. The problem is that the values are formated like this 1234.5600 and i want them to be like 1,234.56
I am trying to have a dropdown in a gridview. I dropdown will hold data from a column in a sql database table. So far, i have this code but when I test the page, the gridview is just pulling the data from the column and displaying it without the dropdown feature. In the code below, "label" is a field in the databaseI have tried to use the info in this walkthrough, but even this does not display the DropDown for me...so I might be doing something wrong.ttp://msdn.microsoft.com/en-us/library/ms178294(VS.80).aspx
Dim Application = From AL In db.AnnualLeave _ Where AL.Approval <> True _ Select LeaveID, EmpID, Name GridView3.DataSource = Application GridView3.DataBind()
after calling `GridView3.DataBind(), why do i still get Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index.
at this line of code GridView3.Columns(1).Visible = False yet the grid has rows and more than 2 columns. i found a thread about similar problem here [URL] Note that the Gridview columns have NOT been defined at design time.
I have a GridView, with a DropDownList as one of the Columns. I can get the SelectedIndexChanged method to trigger - but I cannot figure out how to get other Data regarding which row this triggered on i.e. if I could get the value in the ID column (DocID below), that would be great. My code is a bit too long, so I am just posting snippets. In the *.aspx file I have:
[Code]....
In the *.aspx.cs File:
[Code]....
I am wondering if I can get the DocID from within StatusDropDownList_SelectedIndexChanged - so that I can make appropriate changes to the Database. For e.g. in the RowDataBound event, which I had a GridViewRowEventArgs e, I could easily do e.Row.DataItem - to get the DataItem, I am wondering if I get/do something similar in the SelectedIndexChanged method. (I would prefer this be not the GridView Row Index i.e. I would prefer the DataItem if possible.)
