Retrieving Gridview's Sort Expression And Direction Via Javascript?

Aug 16, 2010

I was given help in a previous topic located here: Accessing Gridview In Another Form In this topic I had gridview rows that are selectable and a search window that returned search results. We found a way for me to select a row in the parent window of the search one. My issue now is that when the parent windows gridview is sorted, the function no longer selects the correct row. I was wondering if there was any way to access the gridviews sort expression and direction, or some other way I can do this so it accounts for sorting. Relavent code is as follow: This is in my parent window

<script type = "text/javascript">
function selectRow(index)
{
//Retrieve a reference to the table that represents the GridView
var gridView = document.getElementById('<%=gvSideList.ClientID%>');
if(gridView)
{
//If able to get a reference to the table representing the GridView...
var doPostbackArgument='Select$'+index;
__doPostBack('<%=gvSideList.ClientID%>',doPostbackArgument);
}
}

This is in the child window

<script type = "text/javascript" >
function selecttherow(index)
{
window.opener.selectRow(index);
}
</script>
protected void gvresults_SelectedIndexChanged(object sender, EventArgs e)
{
//declare variables
GridViewRow row;
int index;
int id;
//retrieve index, row, and id from gvresults
index = gvresults.SelectedIndex;
row = gvresults.Rows[index];
id = Convert.ToInt32(row.Cells[5].Text);
//fill a datatable from general with id's for selection
SqlCommand cmd = new SqlCommand("SELECT ID FROM General", csbg);
cmd.Parameters.AddWithValue("@id", id);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);
//loop through the dt and find the index of the matching id from the search window
for (int i = 0; i < dt.Rows.Count; i++)
{
if (dt.Rows[i]["ID"].Equals(id))
{
//execute script to select the matching row in the dataentry page
string script = "";
script += "selecttherow(";
script += i;
script += ");";
ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), "selecting", script, true);
break;
}
}
}

Let me know if you need me to further clarify anything.

C# - Retrieving The Underlying Dataitems Of Selected Gridview Rows?

Oct 29, 2010

I have a button on the page and a gridview with checkboxes on the first column. The gridview is bound to a List. On buttonClick, I need to retrieve the underlying bound data item (MyEntity) for each selected row. How can I do this? I can't simply recreate MyEntity based on the gridview columns, because I am not displaying all the fields of MyEntity. I need a way to get a hold of MyEntity based on the key (MyEntityId).

Forms Data Controls :: Creating A Click-able GridView Control And Retrieving A ID From A Database?

Mar 16, 2011

On my webpage, jobs.aspx, I have a gridview which is populated from my database. I would like it so that when a row in the gridview is clicked, the ID of the row from my database can then be passed through as a query string to a second webpage, details.aspx, where more information about what was clicked on will be displayed.

I'm confident about being able to pass the query string, I just need help with getting the corresponding row's data ID from my database and making the gridview click-able, which will be the interaction which specifies which ID to be retrieved.

Forms Data Controls :: Gridview With Checkbox Columns Is Retrieving Data Off One Row?

Dec 29, 2010

I've created a data bound gridview to a SQL database. I am retrieving the data with a simple select for a specific date, and then populating my gridview. The one caveat is that I have added a second header row to my gridview, and then I am hiding parts of another row that was retrieved to only populate the main header row. I believe that this is causing my issue. However, when I step through the code it appears that my ids are proper (the first row has an id of 0, etc....). However, when I check the checkbox in row 4, the actual data from row 3 is being pulled out of the gridview.

C# - Retrieving Xml Value Into String

Dec 23, 2010

In the following XML structure how do i retrieve the name value and put this into a string? (i am using a XPathNavigator in my method)

<testsystem>
<test>
<name>one</name>
<name>two</name>
<name>three</name>
</test>
</testsystem>

The name will get displayed in the boundcolumn of a datagrid. I was able to get a attribute with a syntax alike this: (but when changing the xml struture it no longer holds a attribute value)

string name = nav.GetAttribute("name", "")

But have no luck getting the value with a nav as of yet. The purpose is to be able to use it for the following object so i can put name into it.

test t = new test() { Name = name, Questions= new List<Questions>() };

Retrieving DropDownList 'value' (C#/ASP.NET)

Oct 19, 2010

On my page, whenever a DetailsView is updated, I must audit the changes into a database. On most pages this works perfect, as there were just textboxes - however on a page I am working on right now, with dropdownlists, my code isn't working.

Basically, what the code does is captures the Updating event of the SqlDataSource, creates a datareader to look at the contents of the row before it's updated, compares the contents to the parameters in the Update query of the SqlDataSource, and if one has changed to log this in a field in the Audit table. An extract of my code is below:

while (reader.Read())
{
for (int i = 0; i < reader.FieldCount; i++)
{
try {
if (reader[i].ToString() != [code].....

When the control is on a dropdownlist, it seems to never go 'into' the IF even though the fields are different. Do I need to do something special to compare the values of dropdownlists? Note I believe the value is stored as an int in my table.
