Hi,
I'm trying to create an objectdatasource in code and then bind a gridview.
ObjectDataSource objDS = new ObjectDataSource();
objDS.DataObjectTypeName = "VeriWeb_Administration.BusinessObjects.Provider";
objDS.TypeName = "VeriWeb_Administration.BusinessObjects.Providers";
objDS.SelectMethod = "PopulateProviders()";
objDS.UpdateMethod = "Update(Provider item)";
objDS.ID = "ObjectDataSource1";
I get the following error on gridview.databind() :
The Select operation is not supported by ObjectDataSource 'ObjectDataSource1' unless the SelectMethod is specified.
Please help

try this out
objDS.SelectMethod = PopulateProviders;

Hi, thanx for the reply but it has to be a string type.

Hi, thanx for the reply but it has to be a string and PopulateProviders return a list<>
|

Did you try it?
What it's looking for is the name of the function that should be executed.

I have tried:
objDS.SelectMethod = "PopulateProviders"; //The sytax is correct here.
as well as: objDS.SelectMethod = PopulateProviders(); in this instance I get the following error
Cannot implicitly convert type 'System.Collections.Generic.List <veriweb_administration.businessobjects.provider>' to 'string'
ObjectDataSource objDS = new ObjectDataSource();
objDS.DataObjectTypeName = "VeriWeb_Administration.BusinessObjects.Provider";
objDS.TypeName = "VeriWeb_Administration.BusinessObjects.Providers";
objDS.SelectMethod = "PopulateProviders()";
objDS.UpdateMethod = "Update";
objDS.ID = "ObjectDataSource1";
Is the rest of the above code correct? I have never created an objectdatasource is code before.
Thanx again

The solution was that I needed to set the gridview.DataSource = objDS. I previously set the gridview.DataSourceID = "ObjectDataSource1" which I thought is the same.
ObjectDataSource objDS = new ObjectDataSource();
objDS.DataObjectTypeName = "Provider";
objDS.TypeName = "Providers";
objDS.SelectMethod = "PopulateProviders";
objDS.UpdateMethod = "Update";
objDS.ID = "ObjectDataSource1";
The solution was that I needed to set the gridview.DataSource = objDS. I previously set the gridview.DataSourceID = "ObjectDataSource1" which I thought is the same. Everything is working nice.
Thanx

Hello friends........
I am having some problem in my project....
I have to submit the questions in the database but the problem is that if some question are having images then what to do?????
How to save the whole question with the images at its proper location and how to retrieve the question.
Help me plzzzzzzzzz
I want to import bulk of data from the excel sheet....i think if i convert each cell value that is either question or option with or without images to an single image....such as each question and its answer are having unique images...and now save their path in the database and images on the server.........
IS is possible?????

there are a view ways to save images
you can just save the image location in your database table column then write some front end code to access that table and display the image
or you could store the image in the database, this has problems however because you will need a large database if you plan to store lots of images
hope this helps

Thanks Dear,
What to do??
When I have to upload a bulk of data???
It'll not be a good way to load each image...and it'll be very time consuming.........

no can you explain the siutation more?
are users uploading images to your web server?
|
|
|
|
|
No Only Admin will upload papers.
But i want to do this with more flexibility such as just import the excel sheet.......
But i think that i can restrict the admin to set a flag where ever an image come and put the server path of that image between the flags.
So that while retrieveing the text i can find the image path and build a dynamic image on runtime.......
Its my idea is it okay.......

Hey all,
I'm trying to edit my Web.config in runtime, but I get some weird behaviour. Probably something simple I couldn't find on the net. But I'm new to this, so bear with me.
In my code I open the ~/Web.config file and it reads it from the rood of my project folder. When I try to save it to ~/Web.config, it writes it to C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\~\Web.config instead.
How can the same relative path point to 2 places? Read from here but write to there ?!? How do I solve this?
Here is my sample code:
Default.aspx

i dont think its your code i think you just need to make sure you save it to your root folder of your application.
Becausae its a different file to a normal c# file its behaviour is different when you save
Bear in mind i'm not 100% sure on this

How do I make sure? Code a absolute path or something?

I bind datas from qury into a dattabla.Is it possible to set the data in the datatable will be bold.Please help me to answer this query.
|
|
|
|
|
You mean to say that of grid View... Ofcourse you can if you want to set the complete gridView test to Bold. Select the property rowstyle > Font > Bold to true.
If you want only a specific column to be bold
Then select the column > Item Style > Font > Bold = true.
Thanks

The DataTable is a class whose object instances are used to store data. It is not used for presentation purposes, but can used as the datasource for data-bound controls.
I don't know what control you are actually using, but you can embolden HLML text by using either the <b/> tag or through CSS.

No, data is never bold. That's a rendering detail. Of course if you show the data in a grid, or whatever, you can add the HTML to make it render as bold, that's easy. Just put the data binding expression inside <strong> tags
