Forms Data Controls :: Binding DataSet And GridView, Apply Bulk Rows Edit And Update On GridView
Dec 10, 2010
I have a set of dataset with different column retrieved from DB. I need to present the datasets in one GridView (or other ListView etc...) without specifying the column_header. It should present automaticly since the GridView is bind to the DataSet.
In additional, I want this GridView to handle multiple rows edit and update the dataset, idealy, show data in textboxs in initially.How could I set the GridView to edit_model without hardcode column_header and textboxs in 'itemtemplate' or filed.
How could I achieve the bulk edit and update, so that I can assign 'mydataview1.table' to the dataset.
I am following this article in aspsnippets. I followed each and every line, but when the user check the check box, the row become highlighted and it turns light yellow. I could not figure out where the code to make the row yellow/highlighted is and the gridview in my code is not turning yellow either. URL...
I have a grid view that always displays even number of rows. Is it possible to apply same styling for two contineous rows. So for example there would be different background color for rows no 1,2 and 3,4 I would prefer to do that in code behind.
I have a gridview with checkboxlist for each record. I was updating each record individually based on that check, but now they want it to be a bulk update instead of individual. So i have commented out my individual update and added a button below the gridview and created my button event, how to loop thru the gridview and find the checked records and call my update procedure.
i found something kinda close to what i need, but its in VB and not sure how to convert that to C#
I'm having a gridview in my aspx page with checkbox, User can select one or more than one record(s) at a time and clicks on delete button, Then i'm constructing an object of my DTO and adding all the checked row's Primary Key (DataKeyNames - GUID's in my case) to a serializable class and generating an XML and sending it as parameter to the Stored Procedure.
My Doubt is, can i bulk delete all the rows from database table those are present in my XML document??
If it works, I can do bulk update with XML only, i already did bulk insertion by generating an XML..
My Another Question is, Will it affect the performance? Each time when i construct an DTO object and adding it to the Generic List?
Which one is better, I mean ObjectDataSource or SQLDataSource or my XML method?
i have this xml file which i read using the DataSet.ReadXml( path ) method . The tables created from the Xml file is Related in such a maner that each product has many options. Product is in one table and Options are in another.Now all i want to do is display the related tables in One Gridview. For your reference below is the products Xml file,
Now this is what i have done in the Code behind , have a look below
Now the Grid works Great if i want to Display Individual tables out from Dataset but not when they are related . Please do shine your Knowledge on what should be done to display Child ~ Master relationship. By the way , its a definite NO for someone who would show me that link from msdn about displaying XML data using Xmldatasource and gridview [That's a lousy way to display data]
I have webpage with three dropdown boxes on left side (Country Dropdownbox, State Dropdownbox, City Dropdownbox) and these dropdown works independently or one box will depend on another. I have a gridview in right side and the results will be binding to the gridiew by selecting the left side dropdown boxes.
I need to implement the caching technology here because the web page loading very slow due to large amount of records. For example if i select any country from the first dropdown box and the other two boxes are default (Selected text is "ALL"), then It should display records related to selected country in gridview.
Further if I select country and state from the respective boxes then it should display the related records in the gridview like so on. Now i want do some caching functionality to improve the performance. I tried caching the Dataset while binding to gridview but in my case the results will not be static becasue user every time will select different options from different dropdown boxes and results will come based on the selected options.
I have the following problem, i am using gridview to display some table info,, and during RowDataBound event i am binding another DataList control placed on gridview template column,,, the problem is that the DataBind() event of the gridview gives "Index 1 is either negative or above rows count." error.
I debugged alot,, when you disable the DataList binding it works,, but why the 2 not working together i dont know!!.
i want to update the values of the rows on my gridview. there are no errors or warnings about the code, but when i debugged the project i saw that the textboxes i want to change do not change. so there can not be update process.
