I was wondering if when you add the update link for gridview records, is there a way to only allow the user to update just one field in the record?

DataSource Controls :: Relational Field Not Updating On Update?

Mar 1, 2010

I have detailsview with a SQLDataSource to 1 table (City) and am referencing another table (Unit) for one if it's fields.

[code]....

I changed the Unit Code (City Table) field into a template field and am using a dropdownlist item to reference the Unit Name from the (Unit Table) with the CityTable.Unit Code = UnitTable.Unit Code. However when I go into the update and change the dropdownlist item to another Unit Name it is keeping the original Unit Code value or it might even be selecting the first value from the dropdownlist item.

Web Forms :: Updating Text Field Rather Than Gridview?

Feb 26, 2011

I was able to get the code below to give me the value I want from my SQL table however it has to display it in a gridview so I assume that something in the code acutally makes the result a data source rather than a string value.

Forms Data Controls :: Updating Field Value In Gridview Rowupdating Event

Mar 15, 2010

I have a Modified Date and Modified By column in my gridview and I want them to be updated with the current date and current user any time a user updates the row.

I converted my columns to template fields and the textboxes in the edititemtemplate are bound to my sql data columns "ModifiedDate" and "ModifiedBy"

Then I added the attached code in my RowUpdating event.

When I test the code and click the Update link on my gridview I don't get an error but the values don't update either. I put a breakpoint on the code and when I hover over "ModifiedDateLabel.Text" I see the old value of the field so I know I'm accessing the control correctly.

Forms Data Controls :: DataBound GridView Checkbox Field Not Updating SQL?

Jan 14, 2011

So I am uding a GridView bound to a SQL data source.

I have a template feild bound to a SQL BIT

<EditItemTemplate <asp:CheckBox ID="chkSelected" runat="server" Checked='<%# Bind("Selected") %>

The original Item Template was Enabled ="false" I changed this so that you did not have to set the row to a state of edit in order to just select a row. I enabled it so that you could "select" any row with out putting it in a state of edit. the only value changing is if its selected or not. What i am trying to do is use the Data Source Update method to update the bit in the database based on the check box. Currently Update() returns 0. I believe this is because the row/feild is not marked as changed so the Data Source does not see it as something that needs to be updated.

What I am hoping for out of this is post is a way that the rows whom check value has changed to be marked as changed/edited so that the data source will update the database with the values of the check boxes. If all rows are updated this is acceptable as well. I know this is a super simple solution but i have been out of the .NET for a little bit.

Forms Data Controls :: Gridview Copying Data From One Field To Another When Updating

Mar 5, 2010

I have a gridview based on a sqldatasource that has some colums from which two colums showing the data of two fields: field1 and field2. field1 is an ID which should not be updated and therefore it is readonly=true. The sql-query from the sqldatasource is:

SelectCommand="SELECT field1, field2 from anyView"

What I want is, that when a row is updated, then the value from field1 should be copied to field2 The update-query is:

UpdateCommand="UPDATE myTable SET field2=@field2 WHERE field1=@field1"

My idea was, that the @field2 paramter gets the value from the query string out of field1:

<UpdateParameters>
<asp:QueryStringParameter Name="field2" QueryStringField="field1" Type="Int32" />
</UpdateParameters>

But this does not work. Is there an easy way to copy the data from field1 to field2 when updating the row? In addition, is this possible, even if field2 ist not shown in the gridview (i.e. field2 is selected in the query but is not a field in the gridview but should be updated with value of field1).

AJAX :: Gridview's In Update Panel Not Updating

Aug 27, 2010

I have 2 gridviews in an update panel that for some reason will not update. There is no data entry, paging, sorting going on, the data is just there to be displayed. I'm using a timer that initiates every 5 minutes to trigger the updatepanel. I also have an updatepanel on an additional page where I am also using a trigger to fire the updatepanel with 2 charts and 1 oneline/column gridview. The 2 charts update just like they are supposed to however the gridview does not. Here is the code for the 2 Gridview aspx page:

[Code]....

Does anyone know the solution to this issue or if Gridviews just don't refresh in UpdatePanels.

Web Forms :: Gridview Update Not Firing With Required Field Validator?

Feb 17, 2011

I have a gridview that contains a textbox, a drop down, and a checkbox. The commandfield of the gridview has ShowEditButton="true". All of the gridview updating takes place in the "_OnRowUpdating" event. I have a Panel above the gridview with a table and some fields. Everything in the gridview works perfectly, the edit, the update etc., however, when I add a requiredfieldvalidator to the panel above the gridview, the gridview update functionality no longer works. e.g., clicking the update button does not appear to fire. If I comment out the requiredfieldvalidator, everything works fine.

Forms Data Controls :: Formatting Updating An Edit With Template Field?

Jun 26, 2010

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.
