Web Forms :: TextBox Bound To A Decimal Column?
Feb 18, 2011
I have a TextBox bound to a decimal column and want to drop any zeros to right of decimal point. So 8.0000 shows as 8 and 7.6000 shows as 7.6.Currently the Text property is #Bind("Units", "{0:n2}")

I'm trying to populate a date from a bound text field in a DetailsView. I keep getting a error when a DBNull is in the column. How do I avoid the DBNull when populating the text field.My code is as follows:
<asp:TemplateField HeaderText="CBYD Clear Date">
<EditItemTemplate>
<asp:TextBox ID="CBYDExpDate" runat="server" ReadOnly="true" Text='<%# IIf(Eval("CBYDDate") is DBNull.Value,"", String.Format("{0:MM/dd/yyyy}", Eval("CBYDDate").AddDays(30)))%>' />
</EditItemTemplate>
</asp:TemplateField>

I have a DataGrid with a TemplateColumn containing an asp:DropDownList and a BoundColumn. I'd like to have a VB.NET handler for when the selected item in the DropDownList changes. I'd like this handler to also update the value in the BoundColumn with the value of the newly selected item in the DropDownList.
Can someone point me to some resources I can examine to learn how to do this?
If the handler for the selection changing can give me the value of the NEWLY selected item, it should just be a matter of accessing the cell for my BoundColumn in the same row and writing to it. I do not know the syntax to achieve this.

I have a ListView (in an update panel) bound to an ObjectDataSource (connected to an NHibernate object) and in the EditItemTemplate I use Text='<%# Bind("HideLocation")%>' to bind to a string property of the object.
When I click edit (twice, another issue I'm having) and view the code in Chrome, the output looks like this:
[code]....
why the value of the bound data (in this case: In locker 2317) is showing up outside of the text box instead of as the contents of the data?

I have a bound column.
<asp:BoundField DataField="WorkPreference" HeaderText="WorkPreference"
HeaderStyle-HorizontalAlign="Left">
<HeaderStyle HorizontalAlign="Left" />
</asp:BoundField>
dr["WorkPreference"] = sa.WorkPreference ( This is how I bind the data to a DataRow)
The example of the data which gets bound to this column is like the following:
Communications and Marketing Officers; Environmental Assessors; Geologists and Geosciences; Geospatial/Spatial Information Officers;
What I want is that the data should be presented to the user like the following:
Communications and Marketing Officers
Environmental Assessors
Geologists and Geosciences
Geospatial/Spatial Information Officers
In short: I basicaly want to put a break where there is a colon and then bind the data to the gridview. It looks like simple but if you can let me know.

Below is the code behind for a simple aspx page. The web form contains one GridView (GridView1) and one label (Label1). I create a Data Table, then add a row to the table. I then DataBind my GridView to the DataTable. (so far so good) When I run the page I do see the GridView and the single row of data. However the checkbox shown is not enabled, meaning the user cannot uncheck or check it. (As if was not enabled)

ProtectedSub Page_Load(ByVal senderAsObject,ByVal eAs System.EventArgs)HandlesMe.Load

Dim col1AsNew DataColumn

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 grid that is built as well as populated dynamically through c# code. The grid has 3 columns(3 bound fields). And data is being populated in those bound fields through c# code programatically.
Elaborating my question: I have 3 bound field columns(col1, col2 & col3) . I have to increase the rowspan of col2 and col3 headertext's to 2 i.e I want the col2 and col3 header texts to span across two row cells. But the col1 header text should span across just 1 row. And the extra rowscell that is created under col1 due to the increase in the rowspans (of col2 and col3 boundfield headertexts) should be populated with some random text, i.e something like XXXXX

I have a TextBox in a nested FormView that I want to use for entering a date. I have added a calender extender to the TextBox and I want to set TextBox to read only so that the date can only be entered by using the calender extender. This way I can avoid improper date formats.
The problem is that when I enter a new date and click the Update button, the new date is not saved to the database. I have done some searching on the WEB for a solution, and I found that "Page.Form.SubmitDisabledControls = True" is used in the Page_Load event to solve this problem. I have tried this and it does not work.
Another solution that I have seen is to set the control to readonly at runtime in the FormView "ItemCreated" event. I have been unable to access the "ItemCreated" for this FormView because it is nested.

I have a Gridview that has a template field containing a bound textbox (fieldname is 'Status'). I have an extra column containing an update button, which is designed to update the db with whatever is in the textbox.
What's happening is that when I load the form, the textbox is blank, even though there is existing data in the fields. If however I click the update button, all the textboxes in the Status column update and populate with the correct data from the database. I guess my question is why would bound textboxes not populate until an update command is run?

I have an ASP.NET GridView control in a Web Form. For the sake of simplicity, I will say that this GridView is defined as follows:
[code]...
When each of these rows is bound (a.k.a. during the "myGridView_RowBound" event), I want to get the ID, Name, and Age values. My problem is, I cannot figure out how to get the "ID" value. The reason why is because it is in an invisible field.

I read a CSV file into a DataTable.The DataTable in the first image shows each column and type.The types are exactly what they are supposed to be and the data loaded all the rows it was supposed to load.From the second screen shot you can see the database table. SqlBulkCopy is supposed to map column names to database columns by default.According to that logic each column matches up exactly to the database and the column types also match.However,when I run the command it errors on the first row with:
"The given value of type String from the data source cannot be converted to type decimal of the specified target column."
Here is the StackTrace:
"at System.Data.SqlClient.SqlBulkCopy.ConvertValue(Object value, _SqlMetaData metadata) at System.Data.SqlClient.SqlBulkCopy.WriteToServerInternal() at System.Data.SqlClient.SqlBulkCopy.WriteRowSourceToServer(Int32 columnCount) at
[code]...
Anyone have any ideas why this will not import correctly?
