i have given 28 states as a datasource to the dropdownlist..whenever the user enters with id the dropdownlist must populate with his statename not from the first state (A to Z) as it is stored in database.?is thr any option to give query as default value to the dropdown?
View 1 RepliesBelow is a line I have in my ItemTemplate of a FormView. The value in the table is null rather than true/false. Is there any way I can set the default for this to be false if it is null? Or can I do this in my stored procedure in the Select statement to return false if null?
Code:
<asp:CheckBox ID="chkCharges" runat="server" Checked='<%# Bind("MCOverrideCharges") %>'
Text="Yes" Enabled = "False" />
Currently,below is my code.
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
SqlConnection conn = new SqlConnection("Data Source= E\SQLEXPRESS;" + "Initial Catalog=k;Integrated Security=SSPI");
SqlDataAdapter adapSel;
string mySQL = "select column_name from information_schema.columns where table_name='examtimetable' '" + dd_list + "'";....
I receive an error "Incorrect syntax near 'System.Web.UI.WebControls.DropDownList'."
I have a List<string> that I want to use as a datasource for the gridview, making the column a HyperlinkField type and passing the value clicked in the column in the url. My code:
private void DoBind(GridView grid, List<string> Accounts)
{
Hyperlinkfield field = new HyperlinkField();
field.DataNavigateUrlFields = Accounts.ToArray();
field.DataNavigateUrlFormatString = _urlToRedirectFromGrid;
field.DataSource = Accounts;
grid.Columns.Add(field);
grid.AutoGenerateColumns = false;
grid.DataBind();
}
I can't get this to work. The page throws an AJAX null exception when this method is called.
On page load, dropdownlist1 needs to be populated with a list of string objects in a specific table in a sql database. Everytime the selected item in the dropdownlist1 changes, dropdownlist2 needs to be populated with a different table from a database ( I don't know if it can be the same database or not). And it needs to be dynamic, so that everytime the value in dropdownlist1 is changed, the items in dropdownlist2 need to change. All this si being done in VB on a Web Form.
How would I go about doing this? What would the code look like?

Gridview is bound to a table. If a row in table has price greater than zero then the above mentioned Imagebutton should br visible in that row only.
Is it possible to do so.

View 6 RepliesUsing Microsoft Visual Web Developer 2010, I have created a SQL database, with the goal being to create a Lead Management system for my company. I have created two columns: 1 is named InitialCall, and the other is named FollowUp. The InitialCall column has a datatype of "datetime", and currently, the default value setting is (getdate()). The FollowUp column is set to varchar(max), because I want to allow a sales rep to add whatever information they want to.
What I would like to do is change the default value setting in InitialCall from (getdate()), so that it will update that field whenever a sales rep upates the FollowUp field. In essence, this would create a time stamp so that I would know the date and time that the sales rep followed up with a particular lead. What would I enter the default value as?
private void AddDBDataToControl(DataSet app_Support,int count) {
int i = 0; while (count != 0) {
DateTime dt = Convert.ToDateTime(app_Support.Tables[0].Rows[i]["FromDate"].ToString());
//dt=23/08/2010 10:04:00 AM
DropDownList h1 = (DropDownList)GVDate.Rows[i].Cells[1].FindControl("txthour");
h1.SelectedValue = dt.Hour.ToString();
DropDownList m1 = (DropDownList)GVDate.Rows[i].Cells[2].FindControl("txtmin");
m1.SelectedValue = dt.Minute.ToString();
DropDownList h2 = (DropDownList)GVDate.Rows[i].Cells[5].FindControl("txthourto");
DateTime dt2 = Convert.ToDateTime(app_Support.Tables[0].Rows[i]["ToDate"].ToString());

h2.SelectedValue = dt2.Hour.ToString();
DropDownList m2 = (DropDownList)GVDate.Rows[i].Cells[6].FindControl("txtminto");
m2.SelectedValue = dt2.Minute.ToString();
count--; i++; } }
When the function executes
h1.SelectedValue = "10";
and
m1.SelectedValue ="04";
but when it reaches to
count--
h1.SelectedValue takes the value "14"; rather than h1.SelectedValue = "10"; and
h2.SelectedValue = "14";
and
m1.SelectedValue ="25"; rather than m1.SelectedValue ="04"; and
m2.SelectedValue = "25"

when it goes to databind it gives me error asDropDownList1 do not contain binding with ID
I have an array in my code behind page. say:
int[] Hour = new int[24];
I also have a dropdownlist on my aspx page. say:
<asp:dropdownlist id="ddlHour" runat="server">
I want to bind the value of array to the dropdownlist such that when I dropdown the list, I get to see the values from 0 to 24.
I have two tables. t1 and t2
t1 is related to t2 through Order Numbers
these order numbers in table t2 have many part numbers(and hence the need for a second table t2)
I can display t1 using gridview just fine
In that same gridview iI have added a template column containing a dropdownlist(to show partnumbers)
now how can I bind this dropdownlist to the order number so that when the page is loaded the user can click on the dropdownlist to see all the partnumbers associated with that order number.
I am using a dropdown list in gridview and populating it from database.However ,i am getting "object reference not set to an instance ..." error even though i have reference.I have two more similar drop down list and they are working perfectly.
I am uploading the options for the dropdownlist from a "tab delimited" text file for all the dropdown list.I am not getting where exactly the problem is.
<asp:TemplateField HeaderText="Property" HeaderStyle-Wrap="false">
<ItemTemplate>
<asp:Label ID="lblProperty" runat="server" Text='<%#Eval("Property")%>'></asp:Label>

I have a gridview where I can browse an user's information. Through the gridview I'm also able to edit some of this information. A recent change in my client's needs demands that one of these fields is now a DropDownList. This field represents a user's "schedule" (not literally a schedule but works like one), and the different schedule options to be assigned to a user are shown in the drop down list.
Problem: In the drop down list I want to show list items like "9-12 15-17", "10-14 15-18" so that it is easy for the administrator to tell which schedule he's assigning to an user. However, that shouldn't be their actual value. I need "9-12 15-17" to actually be '1' since this is the schedule ID that I'm trying to pass on to the DB.
Here's what I have so far:
[Code]....
And with this last method I change the selected item's value to the Index. Meaning that if I select "9-12 15-17" which has an Index of 1 in the dropDownList, the actual value is now 1. Again, this is the behavior I expect. My experience with ASP is quite little as I'm new on this, but as far as I know, this only actually updates the string array. How would I go about modifying this to reflect my updates on the database? All input is taken into account.
I'm having trouble binding my textbox to my dropdownlist. I got it to work but I don't think it is the correct way of doing it. I have my DDL bound to a datasource and populating everything correctly. However, I couldn't find a better way of binding my textbox to it besides using the FormView control and its counterpart, Templates (edit,insert,etc) It looks messy and i was hoping there was a better way of doing it. I've researched it online for awhile now but I couldn't understand how to implement for my situation.
My DDL has company names in it and the datasource has all the information from the table including what I'm trying to have my textbox pull (Address).
I have a Dropdownlist in an itemTemplate in a gridview. My gridView binds to dataTable1 (from which the selected value for dropdown comes from) and dropDown binds to dataTable2 (i need to get DataValueField and DataTextField from here).

I have a problem in setting the selected index /value in a drop down list. The list is bound by a Linq query and I want to add an item at the top of the list and set it as the selected item.
THis is the code i am using
ListItem li = new ListItem("Select", "", true);
list.DataSource = (from ap in edc.Approvers
where ! ap.approverEmail.Equals("")
orderby ap.approverEmail
select new {ap.approverEmail}).Distinct();
list.DataTextField = "approverEmail";
list.DataValueField = "approverEmail";
list.DataBind();
list.Items.Add(li);
list.Items.FindByText("Select").Selected = true;
The listItem li is the item i want to be first in the list and also selected. Adding this before the databind just loses the item.
I have a dropdownlist used to select a directory for a gridview to show images in the directory.
I am wondering how I can include the value of the dropdownlist in the formatstring or some way to have it change.
I tried
<% "~" & cboFilePath.SelectedValue & "{0}"%>
with no luck. my dropdown containes "/images/" and "/images/uploadedPhotos/" and the gridview lists the files, but the images dont show.
what i have a is a dropdownlist and what i have done is set the datasource to be "select top 10 * from Orders"I have only displayed the OrderID , CustomerID and the Freight i would like to display in a dropdownlist. But what is happening is that for all 10 rows the dame value in the dropdownlist is shown. The dataset that is bound to the dropdownlist initially is all that items in the database.i would like the freight for that particualar Orderid to be displayed even if it is lets say item number 5 in the dropdownlist or itemn number 2 .
View 3 RepliesThe intension is to get the all text file names in the drop down present in a particular location. When a user selects any filename from the drop down, it will show the data which is in that particular text file in a GridView.
I've done both the steps and it's almost complete but i stuck on a small issue. Probably because of non-usage of ASP.NET for a long period of time. The problem is, the drop down only selects the default value not other values.Here's my code for DropDown Selected Index Change
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
DirectoryInfo di = new DirectoryInfo(@"C:myLogs");
