In previous post we have discussed about insert update and delete data in gridview using dataset and table adapter method.
In this post we will learn insert edit update and delete data in gridview control in using SQLConnection and SQLData Adapter method.
If you reset the Data Source at this stage, your values for updating will be lost. I actually don't know how to write the Row Updating function, I just found it from the internet, and so of course it's not working. Please give some references and/or details of how to. Ok what's happening is that you are binding the data source for the Grid View every time a postback occurs in the Page_Load method.
Count ----------- The most common problem for losing new data entered while updating a Grid View or Data Grid is that you are resetting the Data Source for the Grid View or Data Grid in the Page_Load method. I actually don't know how to write the Row Updating function, I just found it from the internet, and so of course it's not working.
This works as expected and I can put a breakpoint in the Row Command event handler to see the "Event" command name.
After it has been clicked the postback places that row in edit mode. At this point in time the above Edit Item Template is displayed with two Image Buttons within it.
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.
Within the Item Template I have an Image Buttong with a Command Name of "Edit".
For understand edit update delete gridview example, First we insert records in to database and select records from database and bind it to gridview control, then update and delete record in gridview using sql dataadater method. Step 7 - Insert record to gridview and update, delete records in gridview.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").In this method we write sql query in our code behind page instead of writing sql stored procedure.
I have a Gridview with Auto Generate Columns="False".
Please help me with writing a Row Updating function in C#, I don't know how to grab the current field's value and also get the old value for one of keys (which is Project Name for editing) of the selected row. the idea wa to don't allow binding the grid view after a post back.
