Combobox datasource remains null even after assigned with a dataset

[Ramya Bhaskaran]

Hi, In my code, if I assign a dataset to the combobox datasource property,it is not getting assigned. The combobox datasource remains null. Because of this the combobox is not getting populated with the data.Can Some one tell me what could be the problem

A couple of things occur. 1. Is this an ASP.NET app? I'm asking, because even though you've posted in the WinForms section I don't want to make any assumptions. If so, you need to call DataBind(). 2. Have you set the DisplayText/DisplayValue?

It is a C# .net application and I have set the Display Member and the value member .The thing is that combobox datasource remains null even after assigned with a dataset.

dataset or datatable?

I have the following code in my application m_DataTable= XmlDataSet.XmlToDataSet(xmlOutput).Tables[0]; While debugging I have checked the value of m_DataTable and it has data.But datasource of the combobox remains null even after assigning. cboTypeID.DataSource = m_DataTable; cboTypeID.DisplayMember = "Play"; cboTypeID.ValueMember = "Play"; cboTypeID.SelectedIndex = -1; The thing is that the same code Works fine in others Systems

I asked if it was an ASP.NET system - not C# (that seemed to be a given). If it's an ASP.NET page, you need to call DataBind() after you set the data source.
