Problem with dropdownlist (resolved)

 

Hi,

 

I am using combobox with dropdownstyle set to dropdownlist. I am populating the value from table to the combo which is bound.

 

cmbPlant.DataBindings.Clear()

cmbPlant.DataSource = l_dvDataView

cmbPlant.DisplayMember = "PlantID"

cmbPlant.Refresh()

 

l_dvView is a dataview which retreives the plantid. I am trying to set the default value to the text property of combobox as below

 

cmbPlant.SelectedIndex = -1

cmbPlant.Text = l_strHomePlantId

cmbPlant.Enabled = False

 

but the value in text property is blank.

 

Please help me

 

Regards

Once you bind the combo, you cannot set the text that way, if the value of l_strHomePlantId is already in the combo then you can do a search in the combo and at that point set the SelectedIndex.

If the value of l_strHomePlantId doesn't exist and you want to add it to the combo you can use the Insert method to insert it at let's say index zero.

SelectedIndex problem

Hello Robby,

 

I am using vs.net 2002 version and developing a project in vb.net. I used the combobox which is bound to the dataview. The combobox is of style DropDownList.

 

I had posted a thread in the forum where i discussed the problem of setting the text value to sonething. The response u sent was to use the search option on the combo box.

 

I used the same as follows to set the selectedindex property.

 

cmbPlant.SelectedIndex = cmbPlant.FindStringExact(l_strHomePlantId)

 

This is working fine here on development machine. If the application is installed on other computer the problem is combobox is blank.

 

Is this a problem in my coding or the problem with version of vb.net i was not able to fig out.

 

Pl help me out in this

.NET Frame work version is different

 

Hi,

 

There is another insight on the same problem.

 

The development machine that is mine is running under the .NET framework version 1.0.3705 and the target machine is having the verion 1.1.432. I don't know whether this is the reason for the above selectedindex problem.

 

Please help me.

It very well could be but I can't be sure.

Perhaps someone else can answer that part.
