I have a DataList bound to a SqlDataSource, but I need to <#%Eval("")%#> a textbox in the same DataList from a different AccessDataSource. Is this possible?
I've got my Drop down list databound to an sql data source, now I need to change the data in a few of the fields before it gets displayed. I've been messing with this all morning and I can't find anything useful, this is what I've got so far and it's clearly not working.
Protected Sub ddlBookType_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles ddlBookType.DataBound 'ddlBookType.Items.Insert(0, "Any") Dim i As Integer For i = 0 To ddlBookType.Items.Count - 1 If ddlBookType.Items(i).Attributes.Equals("mod_cook") Then ddlBookType.Items(i).Text.Replace("mod_cook", "Modern Cooking") End If Next End Sub
i am a new user of asp.net and i am a learner so i just want to connect two dropdownlist to data souce and i want that the list item of second dropdown is changed according to change of selected item of first dropdown.
i have connect it to data source successfully it getting chaged items but it happance only when its load then if i select the next item of first one it would not work properly.
In above SqlDataSource control, I had to pass the SelectParameter (whose value is coming from a ComboBox i.e., whatever comboBox value I selcect from ComboBox, its SelectedValue I had to pass it to the SqlDataSource SelectParameter. I am first time using "SqlDataSource". How to pass the SelectedValue of ComboBox into SlecteParameter of SqlDataSource control ?
I have a dropdownlist that pulls from a datasource. When a name is selected all information drops down to a formview. Once there 3 fields get populated from the dropdownlist and then there is 2 other fields that need user input. Once they hit submit, it should write to a different table in the same DB. I cannot get the fields to populate and write to the DB. Here is my code:
Everything was good before I bumped into the problem when declarative binding (SelectedValue='<# Bind("SvcCluster_Id") >') produced the error, because value has not been found in the list. So i moved binding to the code:
protected void frmConfigEdit_DataBound(Object sender, System.EventArgs e) { if (frmConfigEdit.CurrentMode == FormViewMode.Edit) { var svcCluster_id = DataBinder.Eval(frmConfigEdit.DataItem, "SvcCluster_id"); var ddlCluster = (DropDownList)frmConfigEdit.FindControl("ddlCluster"); if (svcCluster_id != null && ddlCluster.Items.FindByValue(svcCluster_id.ToString()) != null) { ddlCluster.SelectedValue = svcCluster_id.ToString(); } } }
But now seems like this happens later than ObjectDataSource tries to access frmConfigEdit$ddlCluster...
How to manage this?
I wouldn't like to move everything to the code (I mean creating Control parameters, etc)
p.s. Oops, actually it works ok for DataBound event! Sorry.

I have a datalist where each item consists of a textbox and a dropdownlist. I want to get the datakey value when a selected dropdownlist item changes. I can get the selected value of the dropdownlist, but I can't figure out how to get the key field value of the datalist row item that the dropdown resides in.
I have a ddl inside the formview that I can't figure out how to wire up properly. The formview contains detail info, but the ddl needs to list the entire set to items. Then I want the ddl's selected value be set from the recordset intended for the formview. I think it's just a timeing issue s I would like your help. Thanks, - EJM.
