How to assign MaxLength Property to BoundField column in DetailsView COntrol without Converting into TemplateField.
View 3 Replies
I have one two GridViews on a page. One Gridview uses BoundFields inside of the GridView and the Update statement works just fine. The other GridView utilizes TemplateFields due to the fact that Validation Expressions have to be used. I also want This GridView to be able to update the vlues when the user clicks on the Update link on the right side of the GridView. The GridView that uses the BoundFields updates just fine, but the GridView that uses TemplateFields will not update. I have checked and everything is correct other than this difference of BoundField and TemplateField.
View 2 RepliesI have a detailsView whose date values in a cell are currently being displayed in longDateFormat, i want to convert all date values in this DetailsView to short date.
For example, instead of 6/1/2010 12:00:00 AM, i want to display just 6/1/2010
For a Gridview, i can achieve that by the code blow
Protected Sub DetailsView4_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles DetailsView4.DataBound
If e.Row.RowType = DataControlRowType.DataRow Then
For i As Integer = 0 To e.Row.Cells.Count - 1
Dim cellDate As Date
If Date.TryParse(e.Row.Cells(i).Text, cellDate) Then
e.Row.Cells(i).Text = String.Format("{0:d}", cellDate)
End If
Next
End If
End Sub
How can achieve the same with a DetailsView?

View 1 RepliesI am using item template and eval function in the gridview to display the records. Can I add a coulmn which is not in the table?
I have to add some columns which is not in the table and assign the values from code behind to that particular column
I have built a set of custom business objects that I have successfully bound to the GridView and DetailsView controls using the ObjectDataSource. I have been able to provide insert/update/delete functionality and all is working as expected. However, I am trying to wrap this functionality into a custom user control that allows the consumer to specify a table name and a list of column names and have it build this functionality on the fly without regard to the table structure (ie...available columns). I have been able to successfully get the GridView and DetailView to build the columns from code behind and I had all the CRUD working while using 2 panels to show/hide the GridView and DetailsView controls, but I wanted to add some AJAX ability to the control using Matt Berseth's modal popup example to make the interface slicker. The problem I am having is that the EditItemTemplate for the DetailsView control has to be specified in the code behind (because of the flexibile nature of the columns) and I can't figure out how to bind the data from code (rather than having the columns defined and bound in the markup). For all intensive purposes, I am trying to find the code behind counterpart to the following code snippet that binds the data to the textbox:
[Code]....
In my gridview, I have 6 columns. The first 5 columns are filled with data retrieved from database.In the 6th column I want to display a value from textbox from same form. The value should be displayed on the row next to last row of rest of the columns. So my last column (i.e.) 6th column will just have all the rows filled with the same value of the text box.
First 5 columns of grid will be filled by selecting the college name from dropdown.The last colum (Date) must be filled with the date that is given in the textbox.It can be even after button click event(date of attendence).
It can be done after button click event also..

View 2 RepliesI'm using a DataSet to fill my gridview. The dataset contains several columns, like: direction - fromNumber - toNumberThe column direction can contain the values "incoming" or "outgoing". In my gridview, I would like to show only 2 columns, direction and from/to. If direction = "incoming", the values from fromNumber has to be inserted in "from/to". If direction = "outgoing", the values from toNumber has to be inserted in "from/to".I know I can use a TemplateField to show different text values in a column...But I have no idea how to do this when I want to show the values from a column...
<asp:BoundField DataField="direction" HeaderText="direction" HtmlEncode="false" />

A TemplateField of a DetailsView can be assigned a value easily at any of many event handlers such as Load, PreRender, etc. when the page is loaded. However, after Insert or Cancel is clicked, all the fields are cleared. I cannot figure out how to assign a value to the field again in code-behind.

The detailsview is used for logged users to add a new item to a table in my sql database. The detailsview default mode is set to "insert".

I was wondering if anyone could help me. I have a template field which has four itemtemplates that each hold a label in a gridview. These labels are always constant with the same strings. What I want to do is change the css formatting of these four labels depending on the value of a column. So the css formatting would have to be done for each row, not the whole column. I bind the gridview to a dataaccesslayer so there is no sqldatasource on the page. Does anyone have any idea how to do this and where it would be done. I will have the dataview with the data sorted in the correct order. The actual column that is used to alter the CSS will not be in the gridview although I could assign it to the datakeyname if that makes it easier as the data is not sensitive.

View 1 RepliesI have a gridview with databound fields with a checkbox for each row. Only the check box is not bound to any field in the database. I have a button outside of the gridview. By clicking the button, I am trying to get the values of the partyID fields for all the rows that have the check box checked.
Upon clicking the button, nothing gets displayed but no error either.
