Forms Data Controls :: Modify Values In A ObjectDataSouce Before Binding To GridView?
Feb 2, 2011
I need to modify the value of results returned by a Objectdatasource, before binding to the GridView.
More specifically, I need to use Page.ResolveClientUrl() before binding the
RelativePath to the Img Tag-
<ItemTemplate>
<img src='<%#Eval("RelativePath") %>' width="100" height="100" alt='<%#Eval("Name")%>' />
</ItemTemplate>

I am displaying a checkbox in gridview in itemtemplate. It is displayed as checked when the database value is 1 and displayed as unchecked, if the database value is 0. My requirement is when a link button in gridview is clicked, the checkbox, if it is checked should be unchecked and viceversa. Also, I need to save the corresponding values to database. How is this done in the click event of linkbutton. Is there any other method.

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 that displays data from my online database. Works great. edit/update/delete functions work also.
I decided to import data into my database through my SQL Server web admin. It worked fine, and the imported data now shows up in my gridview, but once I decide to use my gridview edit/delete buttons, the grid won't update the data or delete the rows. It will however properly function on the rows that were manually entered with the gridview and/or in visual studio.

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 set of dataset with different column retrieved from DB. I need to present the datasets in one GridView (or other ListView etc...) without specifying the column_header. It should present automaticly since the GridView is bind to the DataSet.
In additional, I want this GridView to handle multiple rows edit and update the dataset, idealy, show data in textboxs in initially.How could I set the GridView to edit_model without hardcode column_header and textboxs in 'itemtemplate' or filed.
How could I achieve the bulk edit and update, so that I can assign 'mydataview1.table' to the dataset.

I have a dataset which I bind to a gridview for display. Normally, the gridview shows the dataset table column name as the column header and the data is bound vertically - i.e. the dataset table rows are created in a vertical/downward fashion. What I would i like do however in my application is to get the GridView to bind in the horizontal direction. So the data that is bound "moves" towards the right. Before suggesting a repearter or datalist, I also have a requirement to not wrap. I have not been successfull getting the repeater/datalist not to wrap unless you know of a setting you can share.

One colunm determines the priority of the message (high, low or no priority assigned) if the message row is empty put nothing in the row else put a ! in the row (to show high priority). Question is don't I need to bind that colunm and row?
'<%#Bind("something")%>' Image="!" />

I have a GridView bound to a DataTable. The DataTable has a Deleted column that holds a boolean value describing whether the row is logically deleted; I need the row to physically remain in the table. Is there a way to skip over rows whose Deleted columns are set to true in the GridView's onRowDataBound event? The closest I could get is marking the row's visibility property to false, but this does not help me because it throws off paging and the GridView's alternating row color.
