I have the DataKey value, I want to use that to get the GridViewRow and retrieve information from various columns - I see lots on information on how to get the datakey from a gridview row, but not the reverse.
My head aches from beating it against the wall for so long. I have a gridview that is populated from a code behind table. The gridview has 3 bound lables, a checkbox (unbound) and another label (unbound). All fields are in template fields. I have coded a vb sub with one command: beep. It fires perfectly every time a user checks the gridview ckeckbox. Here are the columns of the gridview:
1. Player - bound label
2. Description- bound label
3. Amount- bound label
4. ToPay - ckeckbox
5. AmountToPay - unbound label
When a gridviewrow's checkbox is checked (or unchecked) the code determines the check status. If it is checked then the AmountToPay label is to display the same value of the third label (Amount) or it will clear it's text value if the checkbox is unchecking the box. Here is my code:
The gridview:
[Code]....
Here is the vb code that does beep():
[Code]....
I have tried about a dozen ways of reading the checked property of the checkbox but nothing works (sender, e, gridview, rows, items, cells, findcontrol, adnauseum). I want to work the code like this somehow:
If row.Checkbox.checkproperty=true then set lblToBePaid.Text = the lblAmount.Text Else lblToBePaid.Text = "" EndIf
I would like that ID of subcontrol generated from the GridViewRow (NamingContainer) be named including database unique ID.
Exemple :
Suppose in the first colum of my GridView I have a Label displaying the name of an item fetch from a database table.
SQL Database table definition
SQLTable
- UniqueID - Name
In this table I have the following records
- 1956 Hello - 3013 World - ... ...
Suppose I have a GridView having a label (id="lbName") in the first column template.
Now I'm binding GridView using this query : SELECT UniqueID, Name FROM SQLTable
After binding, the HTML result will be :
myGridView_ctl101_lbName
But I would like that NamingContainer names sub items like this :
myGridView_ctl1956_lbName
So I have tried in the RowDataBound event of the GridView : e.Row.NamingContainer.ID = (DataRowView)e.Row.DataItem)["UniqueID"].ToString()At first look it output exactly what I need but after that I can't get working Edit mode, it seem to break DataKeys or something else.
I want to change the value of a literal within a repeater ItemTemplate after postback, based on a value detected at postback.I can't render the whole repeater again though I think because it's actually a radio button in the control that inititates the postback and so I need that control / value to be persisted.
I am using datalist and used custom paging for that but on page index changed there is full postback..because i am sending the values through querystring just have a look to this link
I have a gridview with a dropdownlist in one to the headers. So on the onselect event of the dropdownlist I want to change the assigned values of itemTemplate values inside one of the columns.
Is there an easier way to erase the data from all controls in a gridviewrow than my current approach (code below)?
The problem: When a new type of control is added to the grid, like a radiobutton, it would not get handled here without adding to the code. The tests for type of control can get long and monotonous.
The solution I am seeking: Test the control once for "is WebControl". If it is a web control, cast it and call a single command that would erase its data. Does such a concept exist in ASP.NET 2.0/C#? I know I can do other things on the WebControl level, like set backcolor, but would like to do the same for erasing data.
I tried translating this from vb but getting the error on e.Row.DataItem("CustomerID").ToString i tried varios things but no gooddbSrc.SelectCommand = "SELECT * FROM Orders WHERE CustomerID = '" + e.Row.DataItem("CustomerID").ToString + "' ORDER BY OrderDate";
Which is pretty much eaxactly what I was after! . I have been trying to alter the edit functionality instead of actually having to click on an edit button the user can click anywhere on a selected row to bring up the edit popup window. I have been trying to figure this out for a couple of days and cannot find a way to get it going.
I have a GridView with an alternating Css style. The GridView has a column called tradeId. What I want to show is an alternating colour based on a change in the tradeId. Is this possible? It will make it easier on the eye to group trades together by colour. Here's the GridView code as it is right now:
How to change the values in gridview on text change of templated control without databind again?the value of templated text boxes should change If i change the value of one of the templated textbox then accordingly(By mathematical calculations) the vlaues of all tempated textboxes should also change.
When i run the following code i get an error when gridview changes mode to Edit. stating that you can't change string to decimal!
To get around the occurance i want to disable code when in Edit mode or resolve another way?
GridView1_RowDataBound For Each row As GridViewRow In GridView1.Rows Dim cell As TableCell = row.Cells(7) Dim invoicetotal As Decimal = CDec(cell.Text)
I wanna set a default value in dropdown list when i change in list.....e.g.
I have a dropdown which i have placed in Gridview templates and there is another dropdown jst above that grid....i want...when i change in above dropdown and select a value from that...then that value should be apply in below gridview's dropdown...
As i am selecting 'A' then Gridview's All Dropdowns default value should set 'A'
I have a gridview in which I have several editable fields. The user wants a non-editable field to be modified if another field is modified in the same row. e.g. if Age>=65, Status should ="Retired"
I am using the following demo: [URL]
to create a bulk edit gridview so some columns are automatically editable and others aren't, with a single update button. I can set Status="Retired" in the xml generated, or as a rule in database table. But I'd like the status field in the gridview to change when Age is modified and to be shown to user before they press the single Update button. I'm using update panels and ajax on the page also.
