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.
I ran into this problem I'm sure someone else has similar encounter with, but just couldn't find a solution for it!
I want to disable few entries in the dropdownlist that's in the template field, depending on the value in BoundField when the gridview is being populated.
Below is my attempt:
JobStatus is the dropdownlist in the template field, and Status is the boundfield. In run time, the bolded line causes below exception: Object reference not set to an instance of an object. which I think is wingeing about null variable. Perhaps the templatefields are created after RowDataBound event?
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'm using a formatting expression with a template field. When the details view goes into edit mode the formatting is applied. It looks great because it applies the currency formatting. It shows up as "$60,000.00" instead of "60,000.0000". But then when I do the update it gets rejected because of the $. Is there a way to keep the formatting for the user to see in edit mode but remove the $ when doing the update so I don't get the error?
The error: Exception Details: System.FormatException: Input string was not in a correct format.
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'm using ASP .NET C# 3.5. I have a multiline textbox on my web form that allows for the input of up to 5,000 characters from the end-user. This text is a basic description of a training course. I need to display it out in a clearly formatted way. For example, I need there to be bullets and bold text.
What I did was I chose certain (not often used) characters and then used the .Replace method when displaying the text in an <asp:Label>. If the text in the database contains the character '~' then I replace that with a line break <br />. If it contains '`' I replace that with <b> and if it contains '^' I replace that with </b>.
Is there a better way of doing this? It is working properly, and I'm displaying the text properly, but I know the end-user is going to hate typing text like this for formatting. I do want this all to stay database driven as well

The If - Endif stuff fails with a null reference exception, but the forecolor and backcolor and align code works
