Hi,

We don't provide coding service or advice on implementation. So you can not just give us your requirement and ask us to code for you. You will need to go over the documentation and samples first and ask us if you still have any specific question.

Thanks!

Hi,
I got your point.. I am sorry for keeping those requirements in the forum,

I have taken the same code from the demo link for the drop down values as per my requirement.


http://demo.essentialobjects.com/Demos/Grid/Features/Custom%20Column%20-%20Advanced/Demo.aspx

created a new project as it is and tried with the same C# code which is been used there

protected void Page_Load(object sender, System.EventArgs e)
{
//Get the Repeater control so that we can fill it
//later
EO.Web.CustomColumn productColumn =
(EO.Web.CustomColumn)Grid1.Columns[1];
Repeater productRepeater =
(Repeater)productColumn.EditorInstance.FindControl("Products");

//Fill the repeater from the database
using (DemoDB db = new DemoDB())
{
productRepeater.DataSource = db.ExecuteReader("SELECT * FROM Products");
productRepeater.DataBind();
}
}

protected void Button1_Click(object sender, System.EventArgs e)
{
foreach (EO.Web.GridItem item in Grid1.AddedItems)
{
//Get the product name
string productName = (string)item.Cells[1].Value;

//Get the product quantity. Note user may have
//entered something other than a number, so we
//also check that
int productQty = 0;
try
{
productQty = int.Parse((string)item.Cells[2].Value);
}
catch (Exception ex)
{
System.Diagnostics.Debug.WriteLine(ex.Message);

//Ignore the exception
}

//The Grid provides all the information about what
//have been added/changed, but it does not save them
//to the database for you. You should write code to
//use whatever means that's best/easiest for you to
//save the newly added item here

//Add your code to save productName and productQty
//into the database
}

Label1.Visible = true;
}



My requirements here is...
I am able to bind the data to the grid view (as per using above code)but when we click save the selected value/edited values in the grid is not saving in the data base..(backend)

I am using EO controls first time in .net C# Please help me in finding solution for this
Please let me know any properties needs to be enabled/classes/objects or any setting needs to be done in the aspx.cs page.

Hi,

You really need to read the documentation first. It explained everything step by step. For example, the documentation already explained that the Grid will not automatically save changes for you (so you will need to write code to do so). Yet you are posting sample code as is asking us why your changes are not saved. We are here to help you solving problems, but we are not a shortcut for you to skip the documentation.

Thanks!

Hi
I have gone through the available documents relating to this.. Since i am using EO first time I am unable to find the exact solution..

I have used the same code as i mentioned in the pervious..
I am getting an error at

//Fill the repeater from the database
using (DemoDB db = new DemoDB())
(**** error message: Missing assembly directive/reference)

Iam not sure about this funtionaliy in EO how to call assembly directive/reference..
I will be able write code for save provided i could understood the error message..



I am not sure

Hi,

Please ask someone around you for such compiler errors. Your problem is not that you do not know how to use our product. Your problem is you do not know how to program. You basically just copy code from our samples but couldn't understand any of them.

Please review our support policy here:

http://www.essentialobjects.com/forum/postst1368_Product-support.aspx

It is required that you have basic ASP.NET/HTML/.NET programming knowledge to use our product and there isn't much we can do if you do not know those. We can not afford to assist you on such basic programming errors.

Thanks
