VS 2008 - Selectedvalue In Gridview Dropdown

Jan 26, 2010

I have managed to place a dropdown control iniside a gridview control. The dropdown does indeed populate in each row... How is it possible for the system to correctly select the text in the dropdown based on the value of the field which is driven from the database? Is it to do with the selectedvalue?

AJAX :: Cascading Dropdown Reset SelectedIndex Or Selectedvalue?

Mar 6, 2010

I searched the forum for several days now , but can't find an answer to my problem.

I have 4 Ajax Cascading DropDown named,

ddlCatalogueName > ddlMainGroup > ddlSubGroup > ddlPageNumbers ,

I am passing the values obtained from ddlSubGroup and ddlPageNumbers to a datasource as parameter (Actually to a pageddata ) , on which i create a DataList.

The page is working fine actually but the problem is like the following,</p>

Considering that all dropdown are selected as following :

When i change ddlSubGroup to another one , ddlPageNumbers is populated depending on the number of items divided by 20 ( The datalist is paged by 20 items per time)

then i change the ddlSubGroup(RUBBER PARTS in this example for example to BodyParts , so the dropdown values becomes like :

[code]....

At this point Body PARTS also has page numbers like 1,2,3,4 etc but, it still remains as 2 , however i need the page number to reset back to 1.

Is there any way to do this , and where should i place the code exactly ( which event ) ?

C# - How To Display An Image Based On SelectedValue In A GridView

Nov 4, 2010

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.

Web Forms :: Dropdown Value Used To Filter Another Dropdown Inside A Gridview?

Jun 11, 2010

I'm having a problem with using a dropdown to filter the contents of another drop down. The basic idea is:

Dropdown 1 = CountryList (Column1)
Dropdown 2 = StateList (Column2)

I read the contents of a CSV file and populate the gridview. The user then visually verifies that the data is valid and proceeds to upload to the database. To do some testing, i have intentionally changed spellings of country names so they DO NOT match the countrylist which the grid view then flags with a different background indicating bad data. The user then edits the gridview. The Country and state columns then show a drop down control populated with the country list and filtered states list based on countryID.

Here's the ASP.NET ASPX Source for the section of code that is dealing with the gridview

[Code]....

Here's the section of VB Code behind that deals with handling the "RowEditing", specifically the binding of the dropdowns

[Code]....

The proglem is that these dropdowns are ment to easily fix minor errors in data. When i intentionally changed the spelling of "Canada" to Canadaa", this has no corresponding CountryID in the table and the ddlEdtStateID Dropdown's datasource filter does not work. I tried setting the datasource to nothing if a valid CountryID was not there and then i tried to use the SelectedIndexChanged event for the ddlEditCountryID to programmatically set the datasourceID for ddlEditStateID but when i try using CType(FindControl("ddlEdtStateID"), DropDownList) to set the DataSourceID, it does not find the control.

If the Country does not exist, then i just want the stateslist dropdown to say "select a country" but when a valid country is selected, it should display the filtered list for that countryID. Right now, if bad data is entered for the country, then the program crashes when it tries to populate the state drop down. I want it to just say, select a country when the countryID is not valid.

DataSource Controls :: Filter - Select Date In Ddl And Use Selectedvalue In Gridview SelectCommand

Nov 7, 2010

I've got a gridview which works fine. I use dropdownlists which are filled with distinct values of the columns. So when I select an item in a drompdownlist the gridview refreshes based on the selected value. When I have a column which uses string values, I can start the filter with a default % value to use in my select paramaters. But when I have a date column, I can't use that. I use a datasource for the gridview and I prefer to leave codebehind out if this is not needed. Now I use >= in my gridview select to show all rows. but I want to use only = to make the filter work correct when I select a date in the ddl and use the selectedvalue in the gridview selectCommand

<asp:DropDownList ID="ddlUpdateDatum" DataSourceID="dsPopulateUpdateDatum"
AutoPostBack="true" DataValueField="UPDATEDATE" runat="server"
CssClass="selectinput" AppendDataBoundItems="true">
<asp:ListItem Text="All" Value="01/01/1900"></asp:ListItem>
</asp:DropDownList>
<asp:SqlDataSource ID="dsPopulateUpdateDatum" runat="server"
ConnectionString="<%&#36; ConnectionStrings:GAMSYSTEMSqlServer %>"
SelectCommand="SELECT DISTINCT(UPDATEDATE) FROM [messages] ORDER BY UPDATEDATE ASC ">
</asp:SqlDataSource>
And I use this in the gridview datasource:
<asp:SqlDataSource
runat="server"
ID="dsGridview"
ConnectionString="<%&#36; ConnectionStrings:DBSqlServer %>"
SelectCommand = "SELECT * FROM [messages] WHERE AND UpdateDatum >= @UpdateDatePar ORDER BY UpdateDatumDESC"
>
<SelectParameters>
<asp:ControlParameter Name="UpdateDatePar" ControlID="ddlUpdateDate" PropertyName="SelectedValue" Type="string" />
</SelectParameters>

Setting SelectedValue For One DropDownList Also Updates The SelectedValue For Another DropDownLIst

Jul 21, 2010

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
cooling.SelectedValue: 60 [code]....

I have a gridview with dropdown boxes. As soon as the complete gridview is databound, I want to loop through ALL the rows and set the values of the dropdown boxe in a row based on the value of another column in the same row. The gridview is databound, all data shows up. The condition "If ddl.Items(j).Value = searchstring Then" evaluates as true, but somehow the selected item in the dropdownbox is NOT changed and remains "<ignore>"

.Net GridView With Dropdown List?

Sep 7, 2010

As my previous question didn't seem to have much popularity, I decided to change completely the way I approached the problem. Now my issue is that I still have TABLE1 with a foreign key FK, but what I want to do now is have the FK column in the GridView display Dropdown Lists. The Dropdown Lists should have their Text property bound to FK in TABLE1 but they should be populated by the different values of FK (stored in TABLE2).
