I try to pass two parameters to code behind
Into gridview
Visible='<%# Show(DataBinder.Eval(Container, "DataItem.Id").ToString()) %> + <%# MostrarBotonBorrar(DataBinder.Eval(Container, "DataItem.Rol").ToString()) %>'
in codeBehind:
public bool Show(string value,string value2)
{
if(value == LbluserInvisible.Text)
{
return true;
}
else
{
return false;
}
}
Can anyone explain me that what is the diff between DataBinder.Eval Vs DataBinder.GetPropertyValue?

20 miles
TextBox1 : 'AAA20'
Button:
When user selects 10 miles from dropdownlist DDL1 and types AAA20 in textbox1 which is of type text, on button click it has to pull all the columns from database and show results in gridview using sqldatasource store procedure. I'm stuck in server side code..how to pull the data..in store procedure I'm passing two parameters val1 and val2. val1 gets data from DDL1 and val2 gets data when user types in textbox1 and it has to validate the text...see the code below mentioned and tell me how to pass the params and get the data in gridview...

In one of the web page say "Default1.aspx" I have a Gridview.I am using 2 DataKeyNames in Gridview. i.e., DataKeyNames="G_Name, Param_ID" Also, I have one Hyperlink inside Gridview, upon clicking, page navigates to other page say "Default2.aspx"
code of "Default1" page:
<asp:GridView ID="GridView1" runat="server" DataKeyNames="G_Name, Param_ID" AutoGenerateColumns="False" Width="100%" PageSize="8" AllowPaging="True" OnPageIndexChanging="GridView1_PageIndexChanging">
<Columns>
<asp:BoundField HeaderText="Goal Name" DataField="G_Name" Visible="false"/>
[Code]....
code of "Default2" page:
protected void Page_Load(object sender, EventArgs e) {
if (!Page.IsPostBack) {
string name = Request.QueryString[0].ToString();
string id = Request.QueryString[1].ToString();
}
}
I want to pass multiple parameters in querystring. I wrote above code.
Problem is: I am unable to write the correct syntax for Hyperlink NavigationUrlTherefore, it is giving me below error:
DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'GF_Name, Param_ID'.
at Line:
<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# Eval("GF_Name, Param_ID","~/Default2.aspx?Name={0}&Id={1}") %>'
Text='<%# Eval("GF_Name") %>'></asp:HyperLink>
how to resolve it.
I have big filter coming from database by using storedprocedure. This stored procedure contains about 12 parameters. In asp.net page I select these values and after doing that I want to pass these values to SqlDataSourec which is bound to gridview. How can I pass these values to SqlDataSource, manually in codebehind?
View 8 RepliesI am trying to add a hyperlink to the below listview. This hyperlink passes multiple parameters to the next page? I am trying to achieve the below, works with a gridview but not below.
View 4 RepliesI am creating a grid with a code behind and in the hyper link column I would like to pass some parameters before passing users to a new page. If I just use one parameter, the CustomerID in the dataNavigateUrlFields and dataTextField then the
linkField.DataNavigateUrlFormatString = @"/details.aspx?Customerid={0}";
statment works fine.
Now my requirement is to pass multiple parameters and when I tried the following it gave a
'A field or property with the name 'System.String[]' was not found on the selected data source.'
Here is the code snippet:
HyperLinkField linkField = new HyperLinkField();
string[] dataNavigateUrlFields = { "CustomerID", "CompanyName", "FirstName" };
linkField.DataNavigateUrlFields = dataNavigateUrlFields;
string[] dataTextField = { "CustomerID", "CompanyName", "FirstName" };
linkField.DataTextField = dataTextField.ToString();
linkField.DataTextField = "CustomerID";
linkField.HeaderText = "Customer ID";
linkField.DataNavigateUrlFormatString = @"/details.aspx?Customerid={0}&CompanyName={1}&FirstName={2}";
Does some one know how pass the multiple parameters via the hyperlinkfield in C#?
I need to pass parameters via a gridRowView to a button I have a gridView that currently allows row selection via a radio button What I need to do is based on that selection is pass the parameters to one of 4 button options within the footer. This will then open a new page based on those values. I'd got this working using a hyperLinkButton and querystring but now I'm really struggling with the new requirement "it must be a button" selected this way
Here's my code, if it helps anyone to see it?

How to change storedprocedure in parameter values for sqldata source and update gridview on button click?
I have a gridview and I have an edit template for one control. I have a drop down box in this edit template so that you can select a value from it and then when you hit 'Update' the value from the drop down box is committed to the updated record. Unfortunately when I do hit the update button I get a fault that the "Status" field cannot be null.
Here is the code that picks the value from the drop down value and assigns it to the new values list:

When i remove the hyperlink, the grid is getting displayed. I know, there is something wrong i have coded in the DataNavigateURLformatstring, but not sure what is wrong.
I want to pass the StudentID,CourseID,ChildImageID with the link as the querystring.
I have a asp.net gridview control on my page with several fields and a couple of command fields. However, the update command is giving me problems.
Here is what works. The update command works provided I put straight text into the textboxes that appear. I even have one field that contains a dropdown list which works fine.
Here's the problem. I have two fields that need to access their value programmatically. These fields will reflect the current datetime and the current loggedin user from active directory. I have already created public strings in the C# code.
When I run the edit command on the asp form the grid uses one "DataKeyNames" element. With this the grid can update the selectedrow. However, I haven't been able to access it programmatically in the C# code. I can access the selectedrow in the "selectedindexchanged" event but then I am not able to update my fields in the gridview itself. So, part one of my question is how to I access the "DataKeyNames" properties of a gridview control.
if I can't access the "DataKeyName" property perhaps I could set the label nested within the gridview to the "myCurrentUser()" public string. I am inserting my code to hopefully make this clearer.
i've got a gridview and sql datasource. Its connected to a stored proc that has four optional parameters. In VS when i set up the data source, if i use the test option, and dont supply any values for the sproc, it returns all the values in the table which is what it should do. Now when i try to fill the gridview, it wont return anything at all unless i provide values for all 4 parameters.
It's not even trying to search because i had sql profiler open and nothing shows up until i provide all 4 values. any idea why it's doing this? How do i get it to actually bind even if provide less then all 4 (or none) of the values?
I Have a gridview where I have a link to a details page and I need to pass multiple parameters. I currently have the following:
<Columns>
<asp:BoundField DataField="AssocID" HeaderText="AssocID" InsertVisible="False"
ReadOnly="True" SortExpression="AssocID" />
<asp:BoundField DataField="FirstName" HeaderText="First Name"
SortExpression="FirstName" />
<asp:BoundField DataField="MiddleInitial" HeaderText="M. I."
SortExpression="MiddleInitial" />
<asp:BoundField DataField="LastName" HeaderText="Last Name"
SortExpression="LastName" />
<asp:BoundField DataField="State" HeaderText="State" SortExpression="State" />
<asp:BoundField DataField="EMail1" HeaderText="EMail 1"
SortExpression="EMail1" />
<asp:BoundField DataField="AddrType" HeaderText="Addr Type"
SortExpression="AddrType" />
<asp:HyperLinkField DataNavigateUrlFields="AddrID,AssocID"
DataNavigateUrlFormatString="Details.aspx?AddrID={0}&AssocID={1}" HeaderText="Details"
Text="Details" />
<asp:BoundField DataField="AddrID" HeaderText="AddrID" InsertVisible="False"
ReadOnly="True" SortExpression="AddrID" Visible="False" />
</Columns>
According to all I have read my DataNavagateUrlFields string should work but it isn't. The deal is that any one (AssocID) can have multiple AddrID's associated with it. Regardless of which I choose I only get back the first AddrID for that AssocId.

I have done this with a DropDownList but not 2 text boxes that require date info.
With the DropDownList once a itme is selected from the list the GridView gathers the data in a SQL query and displays it in the same page
I want to have the same type of response when the user enters date data in two text boxes. It would be nice that when they exit the 2nd parameter box to show the grid.
Not sure how to do that in SelectParameters and convert the text data to a date.
I am going to use RequiredFieldValidtors but I am not sure what to do to make sure a valid date is entered.
