Problem in Clientside Grid Binding

[Brijendra Kumar]

Dear Sir/Madam,


I have a grid. and I am binding this grid clientside from an javascript Array.
but when i bind this grid again with an empty array then grid is showing records correctly but
items are not being clear.
Rad Grid binding code that i have written is as follows:

var seltestRows = new Array();
seltestRows[0] = result.rows[0];
seltestRows[1] = result.rows[1];

 

var tableView = $find("<%=gvTest.ClientID %>").get_masterTableView();

 

tableView.set_dataSource(seltestRows);

tableView.dataBind();

Does anyone knows please tell me.

Thanks & Regards

Hi Brijendra,

 In order to assign data source for the grid and refresh its state on the client, utilize the set _dataSource(dataSource) and dataBind() methods from its client-side API. Keep in mind that the data source passed as an argument to the set_dataSource method should have JSON signature which can be serialized by a web service or a page method.
More information about client-side binding is available here.

Kind regards,

Dear Pavlina,

i am using this method to bind grid, following is the code to bind, but when i call Delete_Tests() on a button click then i am first deleting rows from array and then again binding this array, after binding, grid is showing same no of records as in array but after delete action and rebinding grid i again doing a loop of grid items length times then it was showing the previous records, is it rising problem because of using update panel? :

 

function LoadExistingTest() {

 

 

try {

 

arrIndex = 0;

seltestRows = new Array();

 

GetData.GetInquriedTestDetail_N(

OnSuccess_LoadExistingTest);

 

 

return false;

 

}

 

catch (e) {

 

alert(

"Error:- Page -> Test.ascx -> Method -> 'LoadExistingTest' \n Description:- \n" + e.description);

 

 

return false;

 

}

}

 

function OnSuccess_LoadExistingTest(result) {

 

 

try {
for (var i = 0; i < result.rows.length; i++) {

 

 

var row = result.rows[i];

 

seltestRows[arrIndex] = row;

arrIndex++;

}

 

var tableView = $find("<%=gvTest.ClientID %>").get_masterTableView();

 

tableView.set_dataSource(seltestRows);

tableView.dataBind();

return false;

 

}

 

catch (e) {

 

alert(

"Error:- Page -> Test.ascx -> Method -> 'OnSuccess_LoadExistingTest' \n Description:- \n" + e.description);

 

 

return false;

 

}

}

***************
and i have a button to delete records :

function

 

Delete_Tests() {

 

 

try {

 

 

var testCodes = new Array();

 

 

var n = 0;

 

 

var grid = $find("<%=gvTest.ClientID %>").get_masterTableView();

 

 

var cell;

 

 

for (i = 0; i < grid.get_dataItems().length; i++) {

 

cell = grid.get_dataItems()[i]._element.cells[0];

if (cell.childNodes[0].type == "checkbox" && grid.get_dataItems()[i]._element.cells[13].innerText.replace(" ", "") == "") {

 

 

if (cell.childNodes[0].checked == true) {

 

 

var code = grid.get_dataItems()[i]._element.cells[1].innerText;

 

testCodes[n] = code;

n++;

arrIndex--;

 

for (var j = 0; j < seltestRows.length; j++) {

 

 

var row = seltestRows[j];

 

 

if (row.crm_test_test_code_2 == code) {

 

seltestRows.splice(j, 1);

}

}

 

}

}

}

}

GlobalMethods.DeleteTest(testCodes, $get("hdnCustID").value, $get("hdnRefCustomerID").value,

 

$get(

"hdnCallNumber").value, userId_Test, OnSuccess_DeleteTest);
return false;

 

}

 

catch (e) {

 

alert(

"Error:- Page -> Test.ascx -> Method -> 'Delete_Tests' \n Description:- \n" + e.description);

 

 

return false;

 

}

}

 

function OnSuccess_DeleteTest(result) {

 

 

try {
var tableView = $find("<%=gvTest.ClientID %>").get_masterTableView();
tableView.set_dataSource(seltestRows);

 

tableView.dataBind();

 

 

return false;

 

}

 

catch (e) {

 

alert(

"Error:- Page -> Test.ascx -> Method -> 'OnSuccess_DeleteTest' \n Description:- \n" + e.description);

 

 

return false;

 

}

}

Please resolve my prob.

Thanks & Regards

Hi Brijendra,

I went through your code and it looks fine to me. At this point in order to find a quick solution of this matter it will be best if you open a formal support ticket and send us a simple running project (incl. CSS, images, skins, DB backup if needed and so on) demonstrating the problem (and step-by-step instructions on doing so). In that way we can reproduce and pinpoint the problems you're facing on our side and provide a solution.
