Rowupdating how to

I have a Gridview with Auto Generate Columns="False".

I am using a Template Field to display my Edit, Update and Cancel 'buttons' in the first column of the Grid View within respective Item Template and Edit Item Template fields.

A common way to use these collections is to HTML-encode the values supplied by the user before they are stored in the data source.

Place Link Button Edit in Item Template and Link Button Update and Cancel in Edit Tamplate of Gridview's column. Fire Grid View's Row Editing event for Link Button Edit. Fire Grid View's Row Updating event for Link Button Update. Fire Grid View's Row Canceling Edit event for Link Button Cancel. Set Command Name propery of Link Buttons according to their respective event. Set Grid View's Data Key Names Property to record ID (ID=Primary/Unique key of student table) 7.

Save all or press "Ctrl S" and hit "F5" to run the page, the page will look as in the following image: Click on "Edit the Grid View", it will display Textboxes in each cell as in the following image: Edit the value(s) here and click on the Update link, it will update all the data or to remove it click on the "Delete" link above the image shown.

One note will be helpful for you, while describing Columns in Grid View if you are using a boundfield then create objects of the control using cells[index] in the rowupdateing event of Grid View, but if you are using controls itself like Label or textboxes etc then use Fincontrol("stringid").

Otherwise missing cells will be nulled out by the auto update operation. The dictionary consists of the new values to be set on the row's unbound cells.

The hash key is the key of corresponding column and the value is the new value to be set.

If the grid contains templated columns or is bound to some of the fields from the data source, the Values and Old Values must be updated to add those missing values.Within the Item Template I have an Image Buttong with a Command Name of "Edit".This works as expected and I can put a breakpoint in the Row Command event handler to see the "Event" command name.Developer Express Inc disclaims all warranties, either express or implied, including the warranties of merchantability and fitness for a particular purpose.Please refer to the Dev Website Terms of Use for more information.
