I have a dropdownlist in DetailsView to which items are added programmatically during DataBound event. It is working fine in InsertItemTemplate, but in EditItemTemplate i am getting this error "'branchDDL' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value".
I have Gridview inside that i have RadioButtonList,Which is working perfectly. It also bind correctly.
Problem is when user navigate page,the value which was slected in previous page is not apper again.
Gridview is enabled with paging.
I want to save data on SUBMIT button which is outside gridview. So when user clicks this button it should get ALL selectedvalue of radiobuttonlist inside gridview INCLUDING paging and save it to database.
I have tried following code on Button_Click but its not working properly.
I am having Gridview ie : inside i have placeholder, So on Gridview_RowDataBound - according the Specific Condition getting from DB then - i am Creating the Dropdownlist dynamically here and assign Datasource. so up to this its ok. My Problem When the user Select any value on the Dropdownlist on Gridview ,
i have one button outside the Gridview so if i click the button i am want to get the dropdownlist selectedValue so on the Button_Click Event
i used foreach row in the Gridview.. but i do no how to get the value. as the Dropdownlist is create dynamically on Gridview_RowDatabound event. but here what i have to write to get the dropdownlist?
In my asp.net application i'm using gridview to which i'm binding data dynamically by writing a select query in code behined file (all column's are autogenerated) now i want to change gridview cell to edit mode from label to textbox or dropdown on clicking of gridview's cell.How can i achive this in code behined file.
I have a FormView with an EditItemTemplate. In the EditItemTemplate I have a RadioButtonList. I want to populate the selected button from the database. My code looks like this (simplified):
The stored procedure usp_GetOrderDetails returns a char(1) column called "side" which can have values of 'B' or 'S'. If it's a B or an S I want to select the correct item in the RadioButtonList, radSide. Is this possible? I've done it for my Text boxes and dropDownLists on the same form OK, I just can't figure out the RadioButtonList.
I have a GridView and have sortable columns. When a column is sorted the GridView automatically selects the top row, however the SelectedValue is still representing the row before the column is sorted. The SelectedValue of the GridView only gets changed when a row is selected, but I want that to happen when the GridView is sorted.
For example if I have this in my code:
itemId is populated with the old SelectedValue not the new one after the GridView has been sorted.
My page has a gridview, and the gridview has a TemplateField called "Acciones" (Actions). The column Acciones has a ImageButton with CommandName "Select" and CommandArgument "Tutor". Thus, the GridView has controlled event "SelectedIndexChanged". The idea is that in GV_SelectedIndexChanged, I must to set DropDownList's SelectedValue property. But, the value seted in this function don't affect the rendered dropdownlist. The debugger talk's that the value is correctly seted, but the visual result don't.
i want to display selectedvalu on dropdonwlist i have a access table like this;1 Adana2 Ankaraits displaying the numbers of cities but i want to display name of the cities in my gridview how can i fix that ? im using theese codes for register page;
string baglan =DugunSitemiz.Properties.Settings.Default.baglan; OleDbConnection conn = new OleDbConnection(baglan); conn.Open();
Using VB.Net/Asp.Net 2008, web app with Master page.I have a content page where all of the content is wrapped in an UpdatePanel that uses a UserControl called GetEmployee.ascx that I created.
In the user control I have a listbox filled with employeeIDs for the DataValueField, in fact for testing to make sure I'm getting the ID I temporarily set the DataTextField to employeeID also. Anyways I keep getting "" error saying I have not selected anything even when I do so I put a breakpoint and set a watch to find out selectedIndex, value and item and nothing.
after the user selects an employee they should click on the "select employee" button so I have some code there to find out which employee was selected. I have events setup in the GetEmployee.ascx user control to get the value selected:
and I have a breakpoint and it hits the "selectedIndexChanged" event first so I put a watch there and see the following.
I'm populating a dropdownlist in a formview with a different datasource from the formview's. I need to set the selected value according to the value in the formview's datasource but I'm having a hard time doing that.
Here's the code: <asp:FormView ID="FormView1" runat="server" DataKeyNames="ID" DataSourceID="SqlDataSource1"> <EditItemTemplate> [code]....
The question has probably been raised many times, but I could not find an answer so far.The error is: ropdownlist has SelectedValue which is invalid because it does not exist in the list of items.However, I have debugged the values and the list has the correct list of values which includes the SelectedValue.
How would I go about populating a textbox within a FormView with the SelectedValue of a GridView? I'd like to know how to do this with the GridView on the same page as the FormView or a GridView passing a parameter from another page.
I have a form that's being databound with a SQLDataAdapter. I have a DropDownList with a SelectedValue='<%# Bind("FieldName")%>' on it. I was wondering if there was a way I could remove this field and set it dynamically in the codebehind and still have it insert the value of this field with the SQLDataAdapter. The reason for this is because the control I'm using doesn't have a separate InsertItemTemplate, only an EditItemTemplate which serves both purposes, and I need this to dropdownlist to only be databound on Insert.
Right now it's looking like I'll have to stop using the SQLDataAdapter and Update/Insert the data in the codebehind, but I wanted to see if there was something I was missing just-in-case.
I have a drop down list inside a formview control's edititemtemplate and itemtemplate. The dropdown list is not bound to a data source. I am hard-coding the listitems for the drop down list. The formview is bound to a datasource. All I want to do is set the selectedvalue of the dropdown to what is in the record from the database. But I keep getting the error.
<asp:formview .....> <edititemtemplate> .... //some other controls like textboxes that are correctly bound and display the value from the datasource <asp:dropdownlist ID=myddl runat=server cssclass=myclass selectedvalue='<%# eval("mychoice") %>'> <asp:listitem value='0'>I dont know</asp:listitem> <asp:listitem value='1'>Yes</asp:listitem> <asp:listitem value='2'>No</asp:listitem> </asp:dropdownlist .....//rest of the edititem controls that display correctly. </edititemtemplate>
Just for kicks, I added a textbox and set it's value to eval("mychoice") as well and it correctly prints 0,1 or 2. So, I know that there is no illegal value coming back from the datasource. It seems as something with the timing of events - when the listitems are getting bound to the ddl. The error I get is - "myddl has a selectedvalue which is invalid because it does not exist in the list of items".
I have a query that references many tables, however the main record doesnt necessarily have records in the other tables. In my formview itemtemplate, i bind the values of the query but I'm getting an obvious error when the value is null. This is what I'm trying to do: (the field is a boolean btw). These fields are hidden so I don't really care if it gets assigned a temp value or something.
Error: BC30452: Operator '=' is not defined for types 'Object' and 'System.DBNull'.
We use gridview for showing a data from table.It show fine in certain case like in table field dispostion is data and test but in table we put the string Ineligible Member/Member No Longer Enrolled - Spoke to Target and Wrong Number After Skip Tracing then it gives error. 'DropDownList1' has a SelectedValue which is invalid because it does not exist in the list of items.
The following is snippest my code ,tell me where i am wrong.
I've got a gridview which displays records from a table in SQL Server. Next I've got a details view which displays the details from the selected record. This works fine.
When the user selects a record, which then gets displayed in the details view, I'd like to make it possible for the user to edit the record. I've done searchs for this online, and found lots of responses, but none quite displaying an answer to the question I've got. I'm sure it is a simple thing I've done wrong, but at this point I don't know what it is I've done wrong. I've getting this error,"'DropDownList1' has a SelectedValue which is invalid because it does not exist in the list of items.Parameter name: value".
I've got a SqlDataSource to display the data in the details view. And then I specified another SqlDataSource to use for the dropdownlist control in the details view. I converted the field, in the details view, to a template field and have been replacing it. Here's the SqlDataSource controls definitions:
In my asp.net page I have a formview. In the formview's InsertItemTemplate I declare a dropdown list as below:
<td> <asp:DropDownList ID="DropDownList6" runat="server" text='<%# Bind("District") %>' DataSourceID="SqlDataSource6" DataTextField="District" DataValueField="District"> </asp:DropDownList> <asp:SqlDataSource ID="SqlDataSource6" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="SELECT [District] FROM [tblDistricts]"></asp:SqlDataSource> </td> and this works perfectly fine. In the EditItemtemplate I declare a similar dropdownlist as below to edit district values: <td> <asp:DropDownList ID="DropDownList6" runat="server" selectedvalue='<%# Bind("District") %>' DataSourceID="SqlDataSource6" DataTextField="District" DataValueField="District"> </asp:DropDownList> <asp:SqlDataSource ID="SqlDataSource6" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="SELECT [District] FROM [tblDistricts]"></asp:SqlDataSource> </td>
But whenever I try to edit the data I get the error:
'DropDownList6' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value And the values I am trying to edit were entered into the table by the dropdownlist declared in the insertitemtemplate dropdownlist6 listed above. And no values were deleted from the table.
