I have built some back-end code to retrieve an image from a SQL Server database. I want to display this image on my web form based on the currenct selected value of a gridview control.
I have a page called GetImage.aspx which takes two querystring parameters, entityId and entityType. entityId is the GridView.SelectedValue and entityType is simply "T". My code for GetImage.aspx looks like this:
[Code]....
The image is not displayed, however I can see the stored procedure being executed on the database server with the correct ID when I select an item in the GridView, so that part is working, but the display of the image isn't.
I have a gridview that I'd like to have changed based on a value selected in a dropdownlist. I'm able to get the aspx page to display the dropdown list (comming from SQL), and when I select a value, the page reloads, but no data show in the griview.

View 1 RepliesMy 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 have a WebForms page that has two DropDownList controls on it that both contain a range of temperatures from 60-80 degrees, one for heating the other for cooling. They are declared in the .aspx as:
<asp:DropDownList ID="heating" runat="server" />
<asp:DropDownList ID="cooling" runat="server" />
The values for each list are populated in the code-behind using:
for(int i = 60; i <= 80; i++)
{
var listItem = new ListItem(i + " degrees", i.ToString());
heating.Items.Add(listItem);
cooling.Items.Add(listItem);
}
When I try to set the selected value for each DropDownList using the values in an object containing data loaded from the database using:heating.SelectedValue = myHome.avgHeatingTemp.ToString();
cooling.SelectedValue = myHome.avgCoolingTemp.ToString();
The SelectedValue for both lists is set first to the value in myHome.avgHeatingTemp, then to the value in myHome.avgCoolingTemp. Heres what the values are for each variable after each step of the process of setting the SelectedValues:
Initial State
heating.SelectedValue: 60

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]....
I'm using a FormView which has odsMain as the datasource. I am also using a dropdownlist which is being populated with objectdatasource odsddl.
I'd like to set the selectedvalue of the dropdownlist with the value contained in odsMain (the current record value for it). Is there any way this can be done?
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".
in my asp.net and vb code web. i have a drop downlist and a text box.
when i select the item from dropdownlist the numeric value should change accordingly. is it possible
Before this, everything is fine when running the project After I've put "SelectedValue" below to the field,
<asp:TemplateField HeaderText="Interest">
<ItemTemplate>
<asp:DropDownList ID="ddl" OnSelectedIndexChanged="ddl_IndexChanged" SelectedValue='<%# bind("int_id") %>' AutoPostBack="true" runat="server">
</asp:DropDownList>
</ItemTemplate>
